The Wireless-N Gigabit Security Router with VPN is an advanced Internet-sharing network solution for your small business needs. The Router features a built-in 4-Port full-duplex 10/100/1000 Ethernet switch to connect four PCs directly, or you can connect more hubs and switches to create as big a network as you need. Like any wireless router, it lets multiple computers in your office share an Internet connection through both wired and wireless connections. It can also be used as an intranet router to aggregate traffic to a company backbone network. The Router has a built-in access point that supports the latest 802.11n draft specification by IEEE. It also supports 802.11g and 802.11b clients in a mixed environment. The access point can support an 11n data rate of up to 300 Mbps. Besides having a higher data rate, 802.11n technology also promises longer coverage by using multiple antennas to transmit and receive data streams in different directions. Users are encouraged to upgrade their firmware through www.linksys.com when 802.11n specification is finalized by IEEE to ensure compatibility with all the wireless-N devices. The Wireless-N Gigabit Security Router with VPN is equipped with advanced security technologies like Intrusion Prevention System (IPS), Stateful Packet Inspection (SPI) Firewall, IP based Access List (IP ACL), and Network Address Port Translation (NAPT, also called NAT as a more generic term). These technologies work together by providing self-defensive strategy. Malicious attack traffic is identified, classified, and stopped in real time while passing through the Router. Users are encouraged to update their IPS signature file to stay current on stopping malicious worms. The SPI Firewall provides deep packet inspection to analyze packets in network layer (IP) and transport layer (TCP, UDP) to block illegal packet transactions. Users can also use IP based ACL to limit traffic to a specific source, destination and protocol. NAPT allows users to open specific TCP/UDP port numbers to the Internet to provide limited service while minimizing harmful traffic at the same time. The Virtual Private Network (VPN) capability is another security feature that creates encrypted tunnels through the Internet, allowing up to five remote offices and five traveling users to securely connect into your office network from off-site. Users connecting through a VPN tunnel are attached to your company's network with secure access to files, e-mail, and your intranet as if they were in the building. You can also use the VPN capability to allow users on your small office network to securely connect out to a corporate network. The QoS features provide consistent voice and video quality throughout your business. This user guide will give you all the information you need to connect, set up, and configure your Router.

The Wireless-N Gigabit Security Router can connect your local area network (LAN) or a group of PCs interconnected in your home or office to the Internet. You can use one public IP address from the ISP through WAN port and use the routers Network Address Translation (NAT) technology to share this single IP address NAT (Network Address Translation):

among all the users. NAT technology translates IP ddresses of a local area network to a The Routers Network Address Port Translation (NAPT or NAT) technology protects your network of PCs so users different IP address for the Internet. on the Internet cannot see your PCs. This is how your LAN remains private. The Router protects your network by inspecting the first packet coming in through the Internet port before delivery to the final destination on one of the Ethernet ports. The Router inspects Internet port services like the web server, ftp server, or other Internet LAN: the computers and networking products that applications, and, if allowed, it will forward the packet to the appropriate PC on the LAN side. make up your local network Multiple Wireless-N Gigabit Security Routers can also be used to connect multiple LANs together. This usually applies to a medium-sized or larger company where you want to divide your network into multiple IP subnets to increase the intranet throughput and reduce the size of the IP broadcast domain and its interference. In this case, you need one WRVS4400Nv2 for each subnetwork and you can connect all the WAN ports to a second level Router or switch to the Internet. Note that the second level Router only forwards data packets through a wired network so you dont have to use the Wireless-N Gigabit Security Router. You can use any wired router in the Linksys family, e.g. RVS4000, which has 4 LAN ports and 1 WAN port. The following diagram shows an example that consists of two levels of routers and multiple LANs inter-connected together. The wireless network is only available at the first level of router to provide end user connections. The second level router can connect to dedicated Server PCs or routers that aggregates traffic from different LANs. a The Use of IP Addresses IP stands for Internet Protocol. Every device in an IP-based network, including PCs, print servers, and routers, requires an IP address to identify its location, or address, on the network. This applies to both the Internet and LAN connections. There are two ways of assigning IP addresses to your network devices. NOTE: Since the Router is a device that connects two networks, it needs two IP addressesone for the LAN, and one for the Internet. In this User Guide, youll see references to the Internet IP address and the LAN IP address. Since the Router uses NAT technology, the only IP address that can be seen from the Internet for your network is the Routers Internet IP address. However, even this Internet IP address can be hidden on the Internet by suppressing PING response. A static IP address is a fixed IP address that you assign manually to a PC or other device on the network. Since a static IP address remains valid until you disable it, static IP addressing ensures that the device assigned it will always have that same IP address until you change it. Static IP addresses are commonly used with dedicated network devices such as server PCs or print servers. Since a users PC is moving around in a network and is being powered on or off, it does not require a dedicated IP address that could be a precious resource in your network. If you use the Router to share your cable or DSL Internet connection, contact your ISP to find out if they have assigned a static IP address to your account. If so, you will need that static IP address when configuring the Router. You can get the information from your ISP. A dynamic IP address is automatically assigned to a device on the network. This IP address is called dynamic because it is only temporarily assigned to the PC or other device. After a certain time period, it expires and may change. If a PC logs onto the network (or the Internet) and its dynamic IP address has expired, the DHCP server will assign it a new dynamic IP address. Most ISPs use dynamic IP addresses for their customers. By default, the Routers Internet Connection Type is Obtain an IP automatically

(DHCP). For DSL users, many ISPs may require you to log on with a user name and password to gain access to the Internet. This is a dedicated, high-speed connection type called Point-to-Point Protocol over Ethernet

(PPPoE). PPPoE is similar to a dial-up connection, which establishes a PPP session with an ISP server through the DSL connection. The server will also provide the Router with a dynamic IP address to establish a connection to the Internet. A DHCP server can either be located on a designated PC on the network or another network device, such as the Router. The PC or network device obtaining an IP address is called the DHCP client. DHCP frees you from having to assign IP addresses manually every time a new user is added to your network. For this Wireless-N Router, a DHCP client is running on a WAN port for most configurations. A DHCP server is running on the LAN side to provide services. By default, a DHCP server is enabled on the Router. If you already have a DHCP server running on your network, you MUST disable one of the two DHCP servers. If you run more than one DHCP server on your network, you will experience network errors, such as conflicting IP addresses. To disable DHCP on the Router, refer to the Basic Setup section in Chapter 6: Setting Up and Configuring the Router. Static IP address: a fixed address assigned to a computer or device that is connected to a network. Dynamic IP address: a temporary IP address assigned by a DHCP server. DHCP (Dynamic Host Configuration Protocol): a protocol that lets one device on a local network, known as a DHCP server, assign temporary IP addresses to the other network devices, typically computers. IPS is an advanced technology to protect your network from malicious attacks. IPS works together with your SPI Firewall, IP Based Access List (IP ACL), Network Address Port Translation (NAPT), and Virtual Private Network (VPN) to achieve the highest amount of securities. IPS works by providing real-time detection and prevention as an in-line module in a router. The Wireless-N Security Router has hardware-based acceleration for real-time pattern matching for malicious attacks. It actively filters and drops malicious TCP/UDP/ICMP/IGMP packets and can reset TCP connections. This protects your client PCs and servers running various operating systems including Windows, Linux, and Solaris from network worm attacks. However, this system does not prevent viruses attached emails. The signature file is the heart of the IPS system. It is similar to the Virus definition files on your PCs Anti-Virus programs. IPS uses this file to match against packets coming in to the Router and performs actions accordingly. As of today, the Wireless-N Router is shipped with signature file version 1.1.4 and with a total of 1048 rules. The rules cover the following categories: DDoS, Buffer Overflow, Access Control, Scan, Trojan Horse, Misc., P2P, IM, Virus, Worm, and Web Attacks. Customers are encouraged to update their IPS signature file regularly to prevent any new type of attacks on the Internet. Chapter 3: Planning Your Virtual Private Network (VPN) Why do I need a VPN?

Computer networking provides a flexibility not available when using an archaic, paper-based system. With this flexibility, however, comes an increased risk in security. This is why firewalls were first introduced. Firewalls help to protect data inside of a local network. But what do you do once information is sent outside of your local network, when e-mails are sent to their destination, or when you have to connect to your company's network when you are out on the road? How is your data protected?

That is when a VPN can help. VPNs are called Virtual Private Networks because they secure data moving outside of your network as if it were still within that network. When data is sent out across the Internet from your computer, it is always open to attacks. You may already have a firewall, which will help protect data moving around or held within your network from being corrupted or intercepted by entities outside of your network, but once data moves outside of your networkwhen you send data to someone via e-mail or communicate with an individual over the Internetthe firewall will no longer protect that data. At this point, your data becomes open to hackers using a variety of methods to steal not only the data you are transmitting but also your network login and security data. Some of the most common methods are as follows:

1) MAC Address Spoofing Packets transmitted over a network, either your local network or the Internet, are preceded by a packet header. These packet headers contain both the source and destination information for that packet to transmit efficiently. A hacker can use this information to spoof (or fake) a MAC address allowed on the network. With this spoofed MAC address, the hacker can also intercept information meant for another user. 2) Data Sniffing Data sniffing is a method used by hackers to obtain network data as it travels through unsecured networks, such as the Internet. Tools for just this kind of activity, such as protocol analyzers and network diagnostic tools, are often built into operating systems and allow the data to be viewed in clear text. 3) Man in the middle attacks Once the hacker has either sniffed or spoofed enough information, he can now perform a man in the middle attack. This attack is performed, when data is being transmitted from one network to another, by rerouting the vpn (virtual private network): a security measure to protect data as it leaves one network and goes to another over the Internet packet: a unit of data sent over a network These are only a few of the methods hackers use and they are always developing more. Without the security of your VPN, your data is constantly open to such attacks as it travels over the Internet. Data travelling over the Internet will often pass through many different servers around the world before reaching its final destination. That's a long way to go for unsecured data and this is when a VPN serves its purpose. What is a VPN?

A VPN, or Virtual Private Network, is a connection between two endpointsa VPN Router, for instancein different networks that allows private data to be sent securely over a shared or public network, such as the Internet. This establishes a private network that can send data securely between these two locations or networks. This is done by creating a tunnel. A VPN tunnel connects the two PCs or networks and allows data to be transmitted over the Internet as if it were still within those networks. Not a literal tunnel, it is a connection secured by encrypting the data sent between the two networks. There are two popular ways to establish a secured tunnel over the Internet IPsec (IP Security) and SSL

(Secure Sockets Layer). IPsec runs on top of the IP layer and SSL runs over HTTP sessions. IPsec provides better data throughput and SSL offers ease of use without the need of VPN client applications. The Wireless-N Gigabit Security Router supports IPsec VPN for maximum throughput on data security. VPN was created as a cost-effective alternative to using a private, dedicated, leased line for a private network. Using industry standard encryption and authentication techniquesIPsec, short for IP Securitythe VPN creates a secure connection that, in effect, operates as if you were directly connected to your local network. Virtual Private Networking can be used to create secure networks linking a central office with branch offices, telecommuters, and/or professionals on the road (travelers can connect to a VPN Router using any computer encryption: encoding data transmitted in a network ip (internet protocol): a protocol used to send data over a network software: instructions for the computer VPN Router to VPN Router Computer (using the Linksys VPN client software) to VPN Router

. The VPN Router creates a tunnel or channel between two endpoints, so that data transmissions between them are secure. A computer with the Linksys VPN client software can be one of the two endpoints (refer to Appendix C: Using the Linksys QuickVPN Software for Windows 2000 or XP). If you choose not to run the VPN client software, any computer with the built-in IPsec Security Manager

(Microsoft 2000 and XP) allows the VPN Router VPN Router to VPN Router An example of a VPN Router-to-VPN Router VPN would be as follows. At home, a telecommuter uses his VPN Router for his always-on Internet connection. His router is configured with his office's VPN settings. When he connects to his office's router, the two routers create a VPN tunnel, encrypting and decrypting data. As VPNs utilize the Internet, distance is not a factor. Using the VPN, the telecommuter now has a secure connection to the central office's network, as if he were physically connected. For more information, refer to Appendix C: Configuring a Gateway-to-Gateway IPsec Tunnel. Computer (using the Linksys VPN client software) to VPN Router The following is an example of a computer-to-VPN Router VPN. In her hotel room, a traveling businesswoman dials up her ISP. Her notebook computer has the Linksys VPN client software, which is configured with her office's IP address. She accesses the Linksys VPN client software and connects to the VPN Router at the central office. As VPNs utilize the Internet, distance is not a factor. Using the VPN, the businesswoman now has a secure connection to the central office's network, as if she were physically connected.

Figure 4-2: Back Panel The Reset button can be used in one of two ways:

If the Router is having problems connecting to the Internet, press the Reset button for just a second with a paper clip or a pencil tip. This is similar to pressing the Reset button on your PC to reboot it. If you are experiencing extreme problems with the Router and have tried all other troubleshooting measures, press and hold in the Reset button for 10 seconds. This will restore the factory defaults and clear all of the Routers settings, such as port forwarding or a new password. The INTERNET port connects to a cable or DSL modem. The four ETHERNET ports connect to network devices, such as PCs, print servers, or additional switches. The POWER port is where you will connect the included AC power cable.

Chapter 6: Setting Up and Configuring the Router Overview The Wireless Router has been designed to be functional right out of the box with the default settings. However, if you'd like to change these settings, the Wireless Router can be configured through your web browser with the Web-based Utility. This chapter explains how to use the Utility to perform the most basic settings. The Utility can be accessed via web browsers, such as Microsoft Internet Explorer or Mozilla Firefox through the use of a computer that is networked with the Wireless Router. Basic Setup For a basic network setup, most users only need to use the following screens of the Utility:

Setup->WAN Click the Setup tab and then select the WAN screen. Select the appropriate Internet Connection Type according to your ISP if connecting your WAN port to the WAN (DSL or cable modem). Otherwise, most cases can leave the default setting to get a WAN port IP address from a DHCP server. Setup->Advanced Routing Click the Setup tab and then select the Advanced Routing screen. If you are connecting the Router to the Internet, leave the default setting. Otherwise, choose the Intranet Router Operation Mode to disable NAT (Network Address Translation). Management Click the Administration tab and then select the Management screen. Change the access password for the Routers Web-based Utility. The default username and password are admin. Most users will also customize their wireless settings:

Wireless On the Wireless screen, change the default SSID on the Basic Settings Tab. Select the level of security under the Security Settings Tab and complete the options for the selected security mode. When the appropriate security mode is configured, disable SSID Broadcast on the Basic Settings Tab. There are two ways to connect to your Wireless Router for the first time. 1. Connect your PC to one of the four LAN ports on the Router. (Refer to "Chapter 5: Connecting the Router.") Then, configure your PC to obtain IP address automatically through a DHCP server. 2. Although it is not recommended, you can also connect your PC wirelessly to the Wireless Router. Then, configure the wireless interface of your PC to obtain IP address automatically through a DHCP server. It is not recommended, because you can easily lose your connection through wireless configuration changes. To access the Web-based Utility of the Router:

Launch a web browser, such as Internet Explorer or Mozilla Firefox, and enter the Routers default IP address, 192.168.1.1, in the Address field. Press the Enter key. A screen will appear asking you for your User name and Password. Enter admin in the User Name field, and enter your password (default password is admin) in the Password field. Then click the OK button. How to Navigate the Utility The Web-based Utility consists of the following nine main tabs: Setup, Wireless, Firewall, VPN, QoS, Administration, IPS, L2 Switch and Status.

Normally, you assign the first IP address for the Router (e.g. 192.168.1.1) so that you can assign an IP address to other devices starting from the 2nd IP address (e.g. 192.168.1.2). The last address in the subnet is for subnet broadcast (e.g. 192.168.1.255) so that the address cannot be assigned to any host. Maximum Number of DHCP Users. Enter the maximum number of PCs that you want the DHCP server to assign IP addresses to. This number cannot be greater than the available host addresses in the subnet (e.g. 253 for /24 subnet). In order to determine the DHCP IP Address range, add the starting IP address (e.g., 100) to the number of DHCP users. Client Lease Time. This is the amount of time a DHCP client can keep the assigned IP address before it sends a renewal request to the DHCP server. The default value is 0, which actually means one day. Static DNS 1-3. If applicable, enter the IP address(es) of your DNS server(s). WINS The Windows Internet Naming Service (WINS) provides name resolution service

(similar to DNS) in Windows networks. If you use a WINS server, enter that servers IP Address here. Otherwise, leave this blank. Static IP Mapping Static IP Mapping is used to bind a specific IP address to a specific MAC address. This helps external (WAN) users to access LAN servers that are advertised through NAPT port forwarding. You can define up to 50 entries. Static IP Address Enter the IP address to be mapped. MAC Address Enter the MAC address to be mapped. Host Name Enter the host name to be mapped. Click Add to create the entry and add it to the list. To modify an existing entry, select it from the list, edit the appropriate field(s), and then click Modify. To delete an entry, select it and click Remove. IPv6 Ipv6 Address If your network has implemented IPv6, enter the proper IPv6 address in this field. Prefix Length Enter the appropriate IPv6 prefix length.

Advanced Routing Operating Mode Select the Operating mode in which the Router will function. Gateway. This is the normal mode of operation. This allows all devices on your LAN to share the same WAN (Internet) IP address. In the Internet Gateway mode, the NAT

(Network Address Translation) mechanism is enabled. Router. You either need another Router to act as the Internet Gateway, or all PCs on your LAN must be assigned (fixed) Internet IP addresses. In Intranet Router mode, the NAT mechanism is disabled. Dynamic Routing The Router's dynamic routing feature can be used to automatically establish a routing table through a database exchange with peer routers (running the same routing protocol). The Router supports RIP (Routing Information Protocol) versions 1 & 2. RIP (Routing Information Protocol. The Router, using the RIP protocol, calculates the most efficient route for the networks data packets to travel between the source and the destination based upon the shortest paths. RIP Send Packet Version. Choose the version of RIP packets you want to send to peers:

RIPv1 or RIPv2. This should match the version supported by other Routers on your LAN. RIP Recv Packet Version. Choose the version of RIP packets you want to receive from peers:

RIPv1 or RIPv2. This should match the version supported by other Routers on your LAN. Static Routing Sometimes you will prefer to use static routes to build your routing table instead of using dynamic routing protocols. Static routes do not require CPU resources to exchange routing information with a peer router. You can also use static routes to reach peer routers that do not support dynamic routing protocols. Static routes can be used together with dynamic routes. Be careful not to introduce routing loops in your network. To set up static routing, you should add route entries in the routing table that tell the Router where to forward packets to specific IP destinations. Enter the following data to create a static route entry:

1. Select Set Number. Select the set number (routing table entry number) that you wish to view or configure. If necessary, click Delete This Entry to clear the entry. 2. Destination IP Address. Enter the network address of the remote LAN segment. For a standard Class C IP domain, the network address is the first three fields of the Destination LAN IP; the last field should be zero. 3. Subnet Mask. Enter the Subnet Mask used on the destination LAN IP domain. For Class C IP domains, the Subnet Mask is 255.255.255.0. 4. Gateway. If this Router is used to connect your network to the Internet, then your gateway IP is the Routers IP Address. If you have another router handling your networks Internet connection, enter the IP Address of that router instead. 5. Hop Count. This value gives the number of nodes that a data packet passes through before reaching its destination. A node is any device on the network, such as switches, PCs, etc. The maximum hop count value is 16. Show Routing Table button. Click this button to show the routing table established either through dynamic or static routing methods. Inter-VLAN Routing Inter-VLAN Routing Select Enable to allow packets to be routed between VLANs that are in different subnets. The default is Enable. Click the Save Settings button to save the Routing settings, click the Cancel Changes button to undo your changes or click the Show Routing Table button to view the current routing table.

NAPT-PT This allows an IPv6-only host on your LAN to connect to IPv4-only hosts on the WAN using address translation and protocol-translation (per RFC2766). 6to4 This allows your IPv6 network to connect to other IPv6 networks via tunnels through IPv4 (per RFC3056). The remote router also needs to support 6to4 as well. Since the tunnel can be automatically formed based on traffic, there is no limit on how many tunnels you can have. 6to4 Gateway Access Control By default, this route allows 6to4 connections to or from any other 6to4 gateway. By enabling this Access Control, you can have a better control which IPv6 clouds this router is connecting to. A list of IP addresses can be entered in the Access List. Those should be the IPv4 addresses of the remote 6to4 gateways. Permit following sites: Allow only a limited set of 6to4 gateways to establish tunnel with our router. Up to 20 sites can be configured and they can send traffic simultaneously. Block following sites: Prevent a limited set of 6to4 gateways from establishing tunnels with our router. Up to 20 sites can be configured. Static 6to4 DNS entry: Allow users to configure static DNS entry to map hostname to IPv6 address. This will provide a convenient way for users to access remote IPv6 hosts. Click the Save Settings button to save the network settings or click the Cancel Changes button to undo your changes.

Help information is displayed on the right-hand side of the screen. Advanced Wireless Settings This screen allows you to configure the advanced settings for the Wireless Router. The Wireless-N Router adopts several new parameters to adjust the channel bandwidth and guard intervals to improve the data rate dynamically. Linksys recommends to let your Wireless Router automatically adjust the parameters for maximum data throughput. Advanced Settings You can change the following advanced parameters (some only for Wireless-N) for this Wireless Router. Channel Bandwidth. You can select the channel bandwidth manually for Wireless-N connections. When it is set to 20MHz, only the 20MHz channel is used. When it is set to 40MHz, Wireless-N connections will use 40MHz channel but Wireless-B and Wireless-G will still use 20MHz channel. When it is set to Auto, it allows wireless clients to negotiate the bandwidth to use. The default is 20MHz. Guard Interval. You can select the guard interval manually for Wireless-N connections. The two options are Short (400ns) and Long (800ns). The default is Auto. CTS Protection Mode. CTS (Clear-To-Send) Protection Mode function boosts the Wireless Routers ability to catch all wireless transmissions, but will severely decrease performance. Keep the default setting, Auto, so the Wireless Router can use this feature as needed, when the Wireless-N/G products are not able to transmit to the Wireless Router in an environment with heavy 802.11b traffic. Select Disabled if you want to permanently disable this feature. Beacon Interval. This value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the Wireless Router to keep the network synchronized. A beacon includes the wireless networks service area, the Wireless Router address, the Broadcast destination addresses, a time stamp, Delivery Traffic Indicator Maps, and the Traffic Indicator Message (TIM). The default is 100 ms. DTIM Interval. This value indicates how often the Wireless Router sends out a Delivery Traffic Indication Message (DTIM). Lower settings result in more efficient networking, while preventing your PC from dropping into power-saving sleep mode. Higher settings allow your PC to enter sleep mode, thus saving power, but interferes with wireless transmissions. The default is 1 ms. RTS Threshold. This setting determines how large a packet can be before the Wireless Router coordinates transmission and reception to ensure efficient communication. This value should remain at its default setting of 2346. If you encounter inconsistent data flow, only minor modifications are recommended. Change these settings as described here and click Save Settings to apply your changes, or click Cancel Changes to cancel your changes. Help information is displayed on the right-hand side of the screen, and click More for additional details. VLAN & QoS This screen allows you to configure the Qos and VLAN settings for the Access Point. The QoS (Quality of Service) feature allows you specify priorities for different traffic. Lower priority traffic will be slowed down to allow greater throughput or less delay for high priority traffic. The 802.1Q VLAN feature is allowing traffic from different sources to be segmented. Combined with the multiple SSID feature, this provides a powerful tool to control access to your LAN VLAN Enabled/Disabled VLAN. You can enabled this feature only if the hubs/switches on your LAN support the VLAN standard. AP Management VLAN. Define the VLAN ID used for management. VLAN ID. Enter the VLAN ID. QoS U-APSD(WMM Power Save). Select Enabled or Disabled as required. WMM. Wi-Fi Multimedia is a QoS feature defined by WiFi Alliance before IEEE 802.11e was finalized. Now it is part of IEEE 802.11e. When it is enabled, it provides four priority queues for different types of traffic. It automatically maps the incoming packets to the appropriate queues based on QoS settings (in IP or layer 2 header). WMM provides the capability to prioritize traffic in your environment. The default is Enabled. Change these settings as described here and click Save Settings to apply your changes, or click Cancel Changes to cancel your changes. Help information is displayed on the right-hand side of the screen. WDS On this screen you can configure the WDS (Wireless Distribution System) settings for the device. WDS MAC Address.

Help information is displayed on the right-hand side of the screen. Firewall The Firewall Tab allows you to configure software security features like SPI (Stateful Packet Inspection) Firewall, IP based Access List, restriction LAN users on Internet

(WAN port) access, and NAPT (Network Address Port Translation) Settings (only works when NAT is enabled) to limited services to specific ports. Note that for WAN traffic, NAPT settings are applied first, then it will pass the SPI Firewall settings, followed by IP based Access List (which requires more CPU power). Basic Settings Firewall: SPI (Stateful Packet Inspection) Firewall, when you enable this feature, the Router will perform deep packet inspection on all the traffic going through the Router and drop the packets that do not follow the pre-defined protocol behavior. The default is Enable. DoS Protection: When enabled, the Router will prevent DoS (Denial of Service) attacks coming in from the Internet. DOS attacks are making your Routers CPU busy such that it cannot provide services to regular traffic. The default Is Enable. Block WAN Request: When enabled, the Router will ignore PING Request from the Internet so it seems to be hidden. The default is Enable. Remote Management: When enabled, the Router will allow the Web-based Utility to be accessed from the Internet. The default is Disable. Multicast Pass-through: When enabled, the Router will allow IP Multicast traffic to come in from the Internet. The default is Disable. SIP Application Layer Gateway When this feature is enabled, the SIP Application Layer Gateway (ALG) allows Session Initiation Protocol (SIP) packets (used for Voice over IP) to traverse the NAT firewall. This feature can be disabled if the VoIP service provider is using other NAT traversal solutions such as STUN, TURN, and ICE. Block. Select the Web features that you wish to restrict. All those features could place security concern to your PCs on the LAN side. You have to balance your needs on those applications and security. The default is unselected. Java: Java is a programming language for websites. If you deny Java, you run the risk of not having access to Internet sites created using this programming language. Cookies: A cookie is data stored on your PC and used by Internet sites when you interact with them, so you may not want to deny cookies. ActiveX: ActiveX is a Microsoft (Internet Explorer) programming language for websites. If you deny ActiveX, you run the risk of not having access to Internet sites using this programming language. Also, Windows Update uses ActiveX, so if this is blocked, Windows update will not work. Access to Proxy HTTP Server: If local users have access to WAN proxy servers, they may be able to circumvent the Routers content filters and access Internet sites blocked by the Router. Denying Proxy will block access to any WAN proxy servers. Change these settings as described here and click Save Settings to apply your changes, or click Cancel Changes to cancel your changes. Help information is displayed on the right-hand side of the screen, and click More for additional details. IP Based ACL This screen shows a summary of configured IP based Access List. The Access List is used to restrict traffic going through the Router either from WAN or LAN port. There are two ways to restrict data traffic. You can block specific types of traffic according to your ACL definitions. Or you can allow only specific types of traffic according to your ACL definition. The ACL rules will be read according to its priority. If there is a match for a packet, the action will be taken and following lower priority rules will not be checked against this packet. Note that the higher the number of rules that need to be checked against packets, the lower the throughput. Use ACL rules with caution. There are two default rules in the table that cannot be deleted. The first rule will allow all traffic coming in from LAN port to pass the Router. The second rule will allow all traffic coming in from WAN port. These two rules have the lowest priority, so without adding any user defined rules, all the packets can be passed through from both WAN and LAN sides. The rule will be enabled when the Enable button is checked, and when Date and Time are matched. If any of conditions are not met, the rule will not be used to check against packets. The following are descriptions on each of the fields in the ACL Table:

Page Selections: You can select specific page of ACL list from the drop-down menu to be displayed. Or you can navigate them page by page through Previous Page and Next Page button. Priority: This defines the order on which rule is checked against first. The smaller number has higher priority. The default rules will always be checked last. Enable: This tells the Router if the rule is active or not. You can have rules defined in the ACL Table but in an inactive state. The administrator can decide on when to enable specific ACL rules manually. Action: This defines how the rule is to affect the traffic. It can be either Allow or Deny. If the rule is matched and the action is Allow, the packet will be forwarded. If the rule is matched and the action is Deny, the packet will be dropped. Service: This is the service(s) to which the rule applies. Source Interface: Select LAN, WAN, or ANY interface. Source: This is the source IP address, which can be one specific IP address, ANY (all IP addresses), a range of IP addresses, or a specific IP subnet. Destination: This is the destination IP address, which can be one specific IP address, ANY (all IP addresses), a range of IP addresses, or a specific IP subnet. Time: Displays the time period this rule will be enabled (used together with Date). It can be set to Any Time. Day: Displays the days in a week this rule will be enabled (used together with Time). It can be set to Every Day. Edit button: Use this button to go to Edit IP ACL Rule screen and modify this rule. Delete button: Use this button to delete the ACL rule from the list. To add a new rule to the ACL rule table, click Add New Rule and the Edit IP ACL Rule screen appears. Follow the instructions in the section below to create a new ACL rule. To disable all the rules without deleting them, click Disable All Rules. To delete all the rules from the table, click Delete All Rules.

Single Port Forwarding This is one of the NAPT (Network Address Port Translation) feature. Use the Single Port Forwarding screen when you want to open specific services (that use single port). This allows users on the Internet to access this server by using the WAN port address and the matched external port number. When users send these types of request to your WAN port IP address via the Internet, the NAT Router will forward those requests to the appropriate servers on your LAN. Application. Enter the name of the application you wish to configure. External Port. This is the port number used by the service or Internet application. Internet users must connect using this port number. Check with the software documentation of the Internet application for more information. Internal Port. This is the port number used by the Router when forwarding Internet traffic to the PC or server on your LAN and is usually the same as the External Port number. If it is different, the Router performs a Port Translation, so that the port number used by Internet users is different from the port number used by the server or Internet application. For example, you could configure your Web Server to accept connections on both port 80

(standard) and port 8080. Then, enable Port Forwarding, set the External Port to 80 and the Internal Port to 8080. Now, any traffic from the Internet to your Web server will be using port 8080, even though the Internet users used the standard port, 80. (Users on the local LAN can and should connect to your Web Server using the standard port 80.) Protocol. Select the protocol used for this application, TCP or UDP. IP Address. For each application, enter the IP address of the PC running the specific server application. Enabled. Select Enabled to enable port forwarding for the relevant server application.

L2 Switch Tab The Layer 2 Switch Tab provides configurations to the layer 2 switching features on the four Ethernet LAN ports of the Wireless Router. They include VLAN, port configuration, cable diagnostics, and RADIUS authentication. VLAN Create VLAN VLANs are logical subgroups of a Local Area Network (LAN) created via software rather than defining a hardware solution. VLANs combine user stations and network devices into a single domain regardless of the physical LAN segment to which they are attached. VLANs allow network traffic to flow more efficiently within subgroups. VLANs managed through software reduce the amount of time in which network changes are implemented. VLANs have no minimum number of ports, and can be created per unit, per device, per stack, or any other logical connection combination, as VLANs are software based and not defined by physical attributes. VLANs function at layer 2. Since VLANs isolate traffic within the VLAN, a Layer 3 router is needed to allow traffic flow between VLANs. Layer 3 routers identify segments and coordinate with VLANs. VLANs are broadcast and multicast domains. Broadcast and multicast traffic is transmitted only in the VLAN in which the traffic is generated. This device supports up to 4 VLANs, including the default VLAN. VLAN ID The VLAN ID number. This can be any number from 2 to 3290, or from 3293 to 4094. (VLAN ID 1 is reserved for the default VLAN, which is used for untagged frames received on the interface. VLAN IDs 3291-3292 are reserved and cannot be used.) To create a VLAN, enter the ID number and click Add VLAN. VLAN ID Range To create multiple VLANs with a range of ID numbers, enter the starting and ending ID numbers and click Add Range. Delete Selected VLAN To delete a VLAN, select it form the VLAN list and click Delete Selected VLAN. VLAN & Port Assignment This Tab is a combination of Port settings and VLAN membership tabs in one on this device and other routers. The first section is port specific settings regarding the use of VLAN (nothing to do with individual VLANs). It requires users to specify the port mode for each port. The acceptable frame type and PVID options are for General port mode only Port Mode: select one of the three modes:

Access: all the frames are untagged coming in or going out of the switch port. Wireless port can be set to this mode only. Trunk: all the frames are tagged coming in or going out of the switch except for VLAN ID 1 (called native VLAN or default VLAN in Cisco) Note: this cannot be supported on Vitesse 7385 switch chipset. General: all the frames can be tagged or untagged coming in to the switch. If it is untagged, default PVID will apply to the packet. Only the General mode users can choose the following two options. Acceptable Ingress Frame Type:

All Frames: all the incoming frames are acceptable Tagged Only: only tagged incoming frames are acceptable Ingress Filtering: check the VLAN ID on the incoming packet. If the port is a member of this VLAN, accept the frame. Otherwise, drop it. If not enabled, all frames are accepted. PVID: the VLAN ID of the default (untagged) VLAN The following diagram describes the packet flow on General mode. It first checks the filter on acceptable frame type, then check again on ingress filtering option. The second section is per VLAN settings to be used with each port. It requires users to specify each VLAN to be tagged, untagged, or excluded on the specific port. VLAN: Select a VLAN ID to be configured VLAN NAME: VLAN description (read-only) to help user identify this VLAN Tagged: egress frames from this port is tagged for this VLAN Untagged: egress frames from this port is untagged for this VLAN Excluded: this port does not participate in this VLAN at all For Access port, the available options are either untagged or excluded. Therefore, wireless port can set to one of these two modes for each VLAN. Only one of the VLAN ID can be selected (untagged). For Trunk port, the options are tagged or excluded for all VLAN IDs except VLAN 1. VLAN 1 must be untagged. For General port, the options are tagged or untagged for PVID; tagged or excluded for all other VLAN IDs. The third section is a summary of VLAN subscriptions on each port. U means untagged while T means tagged. Radius RADIUS mode provides authentication on devices connecting to the LAN ports. It requires installation of a RADIUS server on your local network. Mode. Select Enabled or Disabled, as desired. RADIUS IP. Enter the RADIUS server IP address. RADIUS UDP Port. Identifies the UDP port. The UDP port is used to verify the RADIUS server authentication. RADIUS Secret. Indicates the Key string used for authenticating and encrypting all RADIUS communications between the Wireless Router and the RADIUS server. This key must match the RADIUS servers configuration. Administration State. Specifies if each port needs RADIUS authentication. The defaults are Force Authorized so no authentication is needed. The possible field values are:

Auto. The controlled port state is set by the RADIUS Mode. Force Authorized. The controlled port state is set to Force-Authorized (forward traffic). All connections can be made. Force Unauthorized. The controlled port state is set to Force-Unauthorized (discard traffic). All connections are blocked.

Appendix A: Troubleshooting This appendix provides solutions to problems that may occur during the installation and operation of the Router. Read the descriptions below to help solve your problems. If you can't find an answer here, check the Linksys website at www.linksys.com. Common Problems and Solutions 1. I need to set a static IP address on a PC. The Router, by default, assigns an IP address range of 192.168.1.100 to 192.168.1.149 using the DHCP server on the Router. To set a static IP address, you can only use the ranges 192.168.1.2 to 192.168.1.99 and 192.168.1.150 to 192.168.1.254. Each PC or network device that uses TCP/IP must have a unique address to identify itself in a network. If the IP address is not unique to a network, Windows will generate an IP conflict error message. You can assign a static IP address to a PC by performing the following steps:

For Windows 98 and Millennium:

A. Click Start, Setting, and Control Panel. Double-click Network. B. In The following network components are installed box, select the TCP/IP-> associated with your Ethernet adapter. If you only have one Ethernet adapter installed, you will only see one TCP/IP line with no association to an Ethernet adapter. Highlight it and click the Properties button. C. In the TCP/IP properties window, select the IP address tab, and select Specify an IP address. Enter a unique IP address that is not used by any other computer on the network connected to the Router. You can only use an IP address in the ranges 192.168.1.2 to 192.168.1.99 and 192.168.1.151 to 192.168.1.254. Make sure that each IP address is unique for each PC or network device. D. Click the Gateway tab, and in the New Gateway prompt, enter 192.168.1.1, which is the default IP address of the Router. Click the Add button to accept the entry. E.

. webpage, try the ping command from a different computer to verify that your original computer is not the cause of the problem. command from a different computer to verify that your original computer is not the cause of the problem. 3. I am not getting an IP address on the Internet with my Internet connection. If you do NOT get a reply, there may be a problem with the connection. Try the ping A. Refer to Problem #2, I want to test my Internet connection to verify that you have connectivity. B. If you need to register the MAC address of your Ethernet adapter with your ISP, please see Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter. If you need to clone the MAC address of your Ethernet adapter onto the Router, see the MAC Address Clone section of Chapter 6: Setting Up and Configuring the Router for details. C. Make sure you are using the right Internet settings. Contact your ISP to see if your Internet connection type is DHCP, Static IP Address, or PPPoE (commonly used by DSL consumers). Please refer to the Basic Setup section of Chapter 6: Setting Up and Configuring the Router for details on Internet Connection Type settings. D. Make sure you use the right cable. Check to see if the Internet LED is solidly lit. E. Make sure the cable connecting from your cable or DSL modem is connected to the Routers Internet port. Verify that the Status page of the Routers Web-based Utility shows a valid IP address from your ISP. F. Turn off the computer, Router, and cable/DSL modem. Wait 30 seconds, and then turn on the Router, cable/DSL modem, and computer. Check the System Summary tab of the Routers Web-based Utility to see if you get an IP address. 4. I am not able to access the Routers Web-based Utility Setup page. A. Refer to Problem #2, I want to test my Internet connection to verify that your computer is properly connected to the Router. B. Refer to Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter to verify that your computer has an IP Address, Subnet Mask, Gateway, and DNS. C. Set a static IP address on your system; refer to Problem #1: I need to set a static IP address. D. Refer to Problem #10: I need to remove the proxy settings or the dial-up pop-up window (for PPPoE users). 5. I cant get my Virtual Private Network (VPN) to work through the Router. Access the Routers web interface by going to http://192.168.1.1 or the IP address of the Router, and go to the VPN => VPN Pass Through tab. Make sure you have IPsec passthrough and/or PPTP passthrough enabled. VPNs that use IPSec with the ESP (Encapsulation Security Payload known as protocol 50) authentication will work fine. At least one IPSec session will work through the Router; however, simultaneous IPSec sessions may be possible, depending on the specifics of your VPNs. VPNs that use IPSec and AH (Authentication Header known as protocol 51) are incompatible with the Router. AH has limitations due to occasional incompatibility with the NAT standard. Change the IP address for the Router to another subnet to avoid a conflict between the VPN IP address and your local IP address. For example, if your VPN server assigns an IP address 192.168.1.X (X is a number from 1 to 254) and your local LAN IP address is 192.168.1.X (X is the same number used in the VPN IP address), the Router will have difficulties routing information to the right location. If you change the Routers IP address to 192.168.2.1, that should solve the problem. Change the Routers IP address through the Basic Setup tab of the Web-based Utility. If you assigned a static IP address to any computer or network device on the network, you need to change its IP address accordingly to 192.168.2.Y (Y being any number from 1 to 254). Note that each IP address must be unique within the network. Your VPN may require port 500/UDP packets to be passed to the computer that is connecting to the IPSec server. Refer to Problem #7, I need to set up online game hosting or use other Internet applications for details. Check the Linksys website at www.linksys.com for more information. 6. I need to set up a server behind my Router. To use a server like a web, ftp, or mail server, you need to know the respective port numbers they are using. For example, port 80 (HTTP) is used for web; port 21 (FTP) is used for FTP, and port 25 (SMTP outgoing) and port 110 (POP3 incoming) are used for the mail server. You can get more information by viewing the A. Access the Routers Web-based Utility by going to http://192.168.1.1 or the IP address of the Router. Go to the Firewall => Single Port Forwarding tab. B. Enable one of the pre-defined applications in the Table or you can add or modify existing entries for your application. C. Enter the IP Address of the server that you want the Internet users to access. For example, if the web servers Ethernet adapter IP address is 192.168.1.100, you would enter 100 in the field provided. Check Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter for details on getting an IP address. Then check the Enable checkbox for the entry. Consider the examples below:

Application Start and End Protocol IP Address Enable Web server FTP server 80 to 80 21 to 21 SMTP (outgoing) 25 to 25 POP3 (incoming) 110 to 110 Both TCP Both Both 192.168.1.100 192.168.1.101 192.168.1.102 192.168.1.102 X X X X When you have completed the configuration, click the Save Settings button. 7. I need to set up online game hosting or use other Internet applications. If you want to play online games or use Internet applications, most will work without doing any port forwarding or DMZ hosting. There may be cases when you want to host an online game or Internet application. This would require you to set up the Router to deliver incoming packets or data to a specific computer. This also applies to the Internet applications you are using. The best way to get the information on what port services to use is to go to the website of the online game or application you want to use. Follow these steps to set up online game hosting or use a certain Internet application:

A. Access the Routers Web-based Utility by going to http://192.168.1.1 or the IP address of the Router. Go to the Firewall => Port Range Forwarding tab. B. Enter the Service Application Name, Range of Port used by this Application, and Layer 4 Protocol used by this Application to the Table. C. Enter the IP Address of the server that you want the Internet users to access. For example, if the web servers Ethernet adapter IP address is 192.168.1.100, you would enter 100 in the field provided. Check Application Start and End Protocol IP Address Enabled UT Halflife 7777 to 27900 Both 192.168.1.100 27015 to 27015 Both 192.168.1.105 PC Anywhere 5631 to 5631 VPN IPSEC 500 to 500 D. Configure as many entries as you like. UDP UDP 192.168.1.102 192.168.1.100 X X X X When you have completed the configuration, click the Save Settings button. 8. I cant get the Internet game, server, or application to work. If you are having difficulties getting any Internet game, server, or application to function properly, consider exposing one PC to the Internet using DeMilitarized Zone

(DMZ) hosting. This option is available when an application requires too many ports or when you are not sure which port services to use. Make sure you disable all the forwarding entries if you want to successfully use DMZ hosting, since forwarding has priority over DMZ hosting. (In other words, data that enters the Router will be checked first by the forwarding settings. If the port number that the data enters from does not have port forwarding, then the Router will send the data to whichever PC or network device you set for DMZ hosting.) Follow these steps to set DMZ hosting:

A. Access the Routers Web-based Utility by going to http://192.168.1.1 or the IP address of the Router. Go to the Firewall => Single Port Forwarding tab. B. Disable or remove the entries you have entered for forwarding. Keep this information in case you want to use it at a later time. C. Go to the Setup => DMZ tab. D. Enter the Ethernet adapters IP address of the computer you want exposed to the Internet. This will bypass the NAT security for that computer. Please refer to Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter for details on getting an IP address. Once completed with the configuration, click the Save Settings button. 9. I forgot my password, or the password prompt always appears when saving settings to the Router. Reset the Router to factory defaults by pressing the Reset button for ten seconds and then releasing it. If you are still getting prompted for a password when saving settings, then perform the following steps:

A. Access the Routers web interface by going to http://192.168.1.1 or the IP address of the Router. Enter the default password admin, and click the Administration =>

Management tab. B. Enter the old password in the Old Password field. C. Enter a different password in the New Password field, and enter the new password in the Confirm New Password field to confirm the password. D. Click the Save Settings button. 10. I am a PPPoE user, and I need to remove the proxy settings or the dial-up pop-up window. If you have proxy settings, you need to disable these on your computer. Because the Router is the gateway for the Internet connection, the computer does not need any proxy settings to gain access. Please follow these directions to verify that you do not have any proxy settings and that the browser you use is set to connect directly to the LAN. For Microsoft Internet Explorer 5.0 or higher:

A. Click Start, Settings, and Control Panel. Double-click Internet Options. B. Click the Connections tab. C. Click the LAN settings button and remove anything that is checked. D. Click the OK button to go back to the previous screen. E. Click the option Never dial a connection. This will remove any dial-up pop-ups for PPPoE users. For Netscape 4.7 or higher:

A. Start Netscape Navigator, and click Edit, Preferences, Advanced, and Proxies. B. Make sure you have Direct connection to the Internet selected on this screen. C. Close all the windows to finish. 11. To start over, I need to set the Router to factory default. Hold the Reset button for up to 30 seconds and then release it. This will return the password, forwarding, and other settings on the Router to the factory default settings. In other words, the Router will revert to its original factory configuration. 12. I need to upgrade the firmware. In order to upgrade the firmware with the latest features, you need to go to the Linksys website and download the latest firmware at www.linksys.com. Follow these steps:

A. Go to the Linksys website at http://www.linksys.com and download the latest firmware. Select the Router from the pull-down menu and choose the firmware from the options. B. Extract the firmware file on your computer. C. To upgrade the firmware, follow the steps in the Upgrade section found in Chapter 6: Setting Up and Configuring the Router. 13. The firmware upgrade failed. The upgrade could have failed for a number of reasons. Follow these steps to upgrade the firmware:

A. Use the Linksys TFTP program to upgrade the firmware. Go to the Linksys website at http://www.linksys.com and download the TFTP program, which will be listed with the firmware. B. Set a static IP address on the PC; refer to Problem #1, I need to set a static IP address. Use the following IP address settings for the computer you are using:

IP Address: 192.168.1.50 Subnet Mask: 255.255.255.0 Gateway: 192.168.1.1 C. Perform the upgrade using the TFTP utility. If the firmware upgrade failed, the Router will still work using its current firmware. 14. My DSL services PPPoE is always disconnecting. PPPoE is not actually a dedicated or always-on connection. The DSL ISP can disconnect the service after a period of inactivity, just like a normal phone dial-up connection to the Internet. There is a setup option to keep alive the connection. This may not always work, so you may need to re-establish connection periodically. A. To connect to the Router, go to the web browser, and enter http://192.168.1.1 or the IP address of B. Enter the password, if asked. (The default password is admin.) C. On the Setup => WAN tab, select the option Keep Alive, and set the Redial Period option at 20 the Router.

(seconds). D. Click the Save Settings button. If the connection is lost again, follow steps E and F to re-establish connection. 15. I can't access my email, web, or VPN, or I am getting corrupted data from the Internet. The Maximum Transmission Unit (MTU) setting may need to be adjusted. By default, the MTU is set at 1500. For most DSL users, it is strongly recommended to use MTU 1492. If you are having some difficulties, perform the following steps:

A. To connect to the Router, go to the web browser, and enter http://192.168.1.1 or the IP address of the Router. B. Enter the password, if asked. (The default password is admin.) C. Go to Setup => WAN tab. D. Look for the MTU option, and select Enable. In the Size field, enter 1492. E. Click the Save Settings button to continue. If your difficulties continue, change the Size to different values. Try this list of values, one value at a time, in this order, until your problem is solved: 1462 1400 1362 1300 16. I need to use port triggering. Port triggering looks at the outgoing port services used and will trigger the Router to open a specific incoming port, depending on which port an Internet application uses. Follow these steps:

A. To connect to the Router, go to the web browser, and enter http://192.168.1.1 or the IP address of the Router. B. Enter the password, if asked. (The default password is admin.) C. Click the Firewall => Port Range Triggering tab. D. Enter any name you want to use for the Application Name. E. Enter the Start and End Ports of the Triggered Port Range. Check with your Internet application provider for more information on which outgoing port services it is using. F. Enter the Start and End Ports of the Forwarded Port Range. Check with your Internet application provider for more information on which incoming port services are required by the Internet application. Once completed with the configuration, click the Save Settings button. Check if other PCs work. If they do, ensure that your workstations IP settings are correct If the PCs are configured correctly, but still not working, check the Router. Ensure that it 17.

Click Internet Options. Click the Security tab. Click the Default level button. Make sure the security level is Medium or lower. Then click the OK button. Frequently Asked Questions What is the maximum number of IP addresses that the Router will support?

The Router will support up to 253 IP addresses if the subnetmask is set to 255.255.255.0. Is IPSec Passthrough supported by the Router?

Yes, enable or disable IPSec Passthrough on the VPN => VPN Pass Through tab. Where is the Router installed on the network?

In a typical environment, the Router is installed between the cable/DSL modem and the LAN. Plug the Router into the cable/DSL modems Ethernet port. Does the Router support IPX or AppleTalk?

No. TCP/IP is the only protocol standard for the Internet and has become the global standard for communications. IPX, a NetWare communications protocol used only to route messages from one node to another, and AppleTalk, a communications protocol used on Apple and Macintosh networks, can be used for LAN to LAN connections, but those protocols cannot connect from the Internet to the LAN. What is Network Address Translation and what is it used for?

Network Address Translation (NAT) translates multiple IP addresses on the private LAN to one public address that is sent out to the Internet. This adds a level of security since the address of a PC connected to the private LAN is never transmitted on the Internet. Furthermore, NAT allows the Router to be used with low cost Internet accounts, such as DSL or cable modems, when only one TCP/IP address is provided by the ISP. The user may have many private addresses behind this single address provided by the ISP. Does the Router support any operating system other than Windows 98, Millennium, 2000, or XP?

Yes, but Linksys does not, at this time, provide technical support for setup, configuration or troubleshooting of any non-Windows operating systems. I set up an Unreal Tournament Server, but others on the LAN cannot join. What do I need to do?

If you have a dedicated Unreal Tournament server running, you need to create a static IP for each of the LAN computers and forward ports 7777, 7778, 7779, 7780, 7781, and 27900 to the IP address of the server. You can also use a port forwarding range of 7777 to 27900. If you want to use the UT Server Admin, forward another port (8080 usually works well but is used for remote admin. You may have to disable this.), and then in the [UWeb.WebServer] section of the server.ini file, set the ListenPort to 8080 (to match the mapped port above) and ServerName to the IP assigned to the Router from your ISP. Can multiple gamers on the LAN get on one game server and play simultaneously with just one public IP address?

It depends on which network game or what kind of game server you are using. For example, Unreal Tournament supports multi-login with one public IP. How do I get Half-Life: Team Fortress to work with the Router?

The default client port for Half-Life is 27005. The computers on your LAN need to have +clientport 2700x added to the HL shortcut command line; the x would be 6, 7, 8, and on up. This lets multiple computers connect to the same server. One problem: Version 1.0.1.6 wont let multiple computers with the same CD key connect at the same time, even if on the same LAN (not a problem with 1.0.1.3). As far as hosting games, the HL server does not need to be in the DMZ. Just forward port 27015 to the local IP address of the server computer. How can I block corrupted FTP downloads?

If you are experiencing corrupted files when you download a file with your FTP client, try using another FTP program. The web page hangs; downloads are corrupt, or nothing but junk characters are being displayed on the screen. What do I need to do?

Force your Ethernet adapter to 10Mbps or half duplex mode, and turn off the Auto-negotiate feature of your Ethernet adapter as a temporary measure. (Please look at the Network Control Panel in your Ethernet adapters If all else fails in the installation, what can I do?

Reset the Router by holding down the Reset button for ten seconds. Reset your cable or DSL modem by powering the unit off and then on. Obtain and flash the latest firmware release that is readily available on the Linksys website, www.linksys.com. How can I be notified of new Router firmware upgrades?

All Linksys firmware upgrades are posted on the Linksys website at www.linksys.com, where they can be downloaded for free. The Routers firmware can be upgraded using the Web-based Utility. If the Routers Internet connection is working well, there is no need to download a newer firmware version, unless that version contains new features that you would like to use. Downloading a more current version of Router firmware will not enhance the quality or speed of your Internet connection, and may disrupt your current connection stability. Will the Router function in a Macintosh environment?

Yes, but the Routers setup pages are accessible only through Internet Explorer 5.0 or Netscape Navigator 5.0 or higher for Macintosh. I am not able to get the web configuration screen for the Router. What can I do?

You may have to remove the proxy settings on your Internet browser, e.g., Netscape Navigator or Internet Explorer. Or remove the dial-up settings on your browser. Check with your browser documentation, and make sure that your browser is set to connect directly and that any dial-up is disabled. Make sure that your browser is set to connect directly and that any dial-up is disabled. For Internet Explorer, click Tools, Internet Options, and then the Connection tab. Make sure that Internet Explorer is set to Never dial a connection. For Netscape Navigator, click Edit, Preferences, Advanced, and Proxy. Make sure that Netscape Navigator is set to Direct connection to the Internet. What is DMZ Hosting?

Demilitarized Zone (DMZ) allows one IP address (computer) to be exposed to the Internet. Some applications require multiple TCP/IP ports to be open. It is recommended that you set your computer with a static IP if you want to use DMZ Hosting. To get the LAN IP address, see Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter. If DMZ Hosting is used, does the exposed user share the public IP with the Router?

No. Does the Router pass PPTP packets or actively route PPTP sessions?

The Router allows PPTP packets to pass through. Is the Router cross-platform compatible?

Any platform that supports Ethernet and TCP/IP is compatible with the Router. How many ports can be simultaneously forwarded?

Theoretically, the Router can establish 4,000 sessions at the same time, but you can only forward 30 ranges of ports. Does the Router replace a modem? Is there a cable or DSL modem in the Router?

No, this version of the Router must work in conjunction with a cable or DSL modem. Which modems are compatible with the Router?

The Router is compatible with virtually any cable or DSL modem that supports Ethernet. What is the maximum number of VPN sessions allowed by the Router?

The maximum number depends on many factors. At least one IPSec session will work through the Router; however, simultaneous IPSec sessions may be possible, depending on the specifics of your VPNs. How can I check whether I have static or DHCP IP addresses?

Ask your ISP to find out. How do I get mIRC to work with the Router?

Under the Firewall => Single Port Forwarding tab, set port forwarding to 113 for the PC on which you are using mIRC. If your questions are not addressed here, refer to the Linksys website, www.linksys.com.
