C-1 viii CHAPTER 1 INTRODUCTION Congratulations on your purchase of the ADSL router. We are proud to provide you with a powerful yet simple communication device for connecting your local area network (LAN) to the Internet. For those who want to surf the Internet in the most secure way, the ADSL router provides a convenient and powerful solution. About the ADSL router The ADSL router provides Internet access to multiple users by sharing a single-user account. Support is provided for both wired and wireless devices. New technology provides wireless security via Wired Equivalent Privacy (WEP) encryption and MAC address filtering. It is simple to configure and can be up and running in minutes. Features and Benefits Built-in ADSL2/2+ modem - supports download speeds up to 24Mbps Local network connection via four 10/100 Mbps Ethernet ports Built-in IEEE802.11g 54Mbps Wireless Access Point (AP) DHCP for dynamic IP configuration, and DNS for domain name mapping 1-1 INTRODUCTION Firewall with Stateful Packet Inspection, client privileges, intrusion detection, and NAT NAT also enables multi-user Internet access via a single user account, and virtual server functionality (providing protected access to Internet services such as web, FTP, e-mail, and Telnet) VLAN and QoS (Quality of Service) support User-definable application sensing tunnel supports applications requiring multiple connections Easy setup through a web browser on any operating system that supports TCP/IP Applications Many advanced networking features are provided by the ADSL router:

Wireless and Wired LAN The ADSL router provides connectivity to 10/100 Mbps devices, and wireless IEEE 802.11g compatible devices, making it easy to create a network in small offices or homes. Internet Access This device supports Internet access through an ADSL connection. Since many DSL providers use PPPoE or PPPoA to establish communications with end users, the ADSL router includes built-in clients for these protocols, eliminating the need to install these services on your computer. 1-2 APPLICATIONS Shared IP Address The ADSL router provides Internet access for up to 253 users via a single shared IP address. Using only one ISP account, multiple users on your network can browse the web at the same time. Virtual Server If you have a fixed IP address, you can set the ADSL router to act as a virtual host for network address translation. Remote users access various services at your site using a constant IP address. Then, depending on the requested service (or port number), the ADSL router can route the request to the appropriate server (at another internal IP address). This secures your network from direct attack by hackers, and provides more flexible management by allowing you to change internal IP addresses without affecting outside access to your network. DMZ Host Support Allows a networked computer to be fully exposed to the Internet. This function is used when NAT and firewall security prevent an Internet application from functioning correctly. Security The ADSL router supports security features that deny Internet access to specified users, or filter all requests for specific services that the administrator does not want to serve. The firewall also blocks common hacker attacks, including IP Spoofing, Land Attack, Ping of Death, IP with zero length, Smurf Attack, UDP port loopback, Snork Attack, TCP null scan, and TCP SYN flooding. WEP (Wired Equivalent Privacy), SSID Broadcast disable, and MAC filtering provide security over the wireless network. 1-3 CHAPTER 2 INSTALLATION Before installing the ADSL router, verify that you have all the items listed under the Package Contents list. Also be sure that you have all the necessary cabling before installing the ADSL router. After installing the ADSL router, refer to Configuring the ADSL Router on page 4-1.

When a switch hears a group join message from a host, it notes which switch interface it heard the message on, and adds that interface to the group. Similarly, when a Layer 2 switch hears a group leave message or a response timer expires, the switch will remove that hosts switch interface from the group. IGMP Querier: if the IGMP Querier is enabled, then the router will periodically query all multicast group members on the specified VLAN. 4-24 ADVANCED SETUP Wireless The ADSL router also operates as a wireless access point, allowing wireless computers to communicate with each other. To configure this function, all you need to do is enable the wireless function, define the radio channel, the SSID, and the security options. Enable or disable Wireless module function: check Enable and then click SAVE SETTINGS. 4-25 CONFIGURING THE ADSL ROUTER Channel and SSID You must specify a common radio channel and SSID (Service Set ID) to be used by the ADSL router and all of its wireless clients. Be sure you configure all of its clients to the same values. Parameter SSID SSID Broadcast Wireless Mode Channel Description Service Set ID (SSID) is the name given to the wireless network. The SSID must be the same on the ADSL router and all of its wireless clients. Enable or disable the broadcasting of the SSID. Disabling broadcasting of the SSID provides added security by hiding your wireless network. This device supports both 11g and 11b wireless networks. Make your selection depending on the type of wireless network that you have. The radio channel used by the wireless router and its clients to communicate with each other. This channel must be the same on the ADSL router and all of its wireless clients. The ADSL router will automatically assign itself a radio channel, or you may select one manually. 4-26 ADVANCED SETUP WLAN MAC Filter Using this MAC filter functionality, you can restrict wireless access based on MAC address. Each PC has a unique identifier known as a Medium Access Control (MAC) address. With MAC filtering enabled, the computers whose MAC address you have listed in the filtering table will be able to connect (or will be denied access) to the ADSL router. Enable MAC Filtering: select to turn on/off this feature. Access Rule for registered MAC address: select to allow/deny access for the registered MAC addresses. Selecting Allow means only MAC addresses registered here will be able to connect to the router. Selecting Deny means only the MAC addresses registered here will be denied access to the router. MAC Filtering table: enter the MAC address in the table, or you can use the option to quickly copy the currently associated client entry to the MAC Filtering table. 4-27 CONFIGURING THE ADSL ROUTER Security To make your wireless network safe, you should turn on the security function. The ADSL router supports WEP (Wired Equivalent Privacy), WPA (Wi-Fi Protected). Three options are available:

No WEP, No WPA WEP only WPA only 4-28 ADVANCED SETUP WEP If you want to use WEP to protect your wireless network, you need to set the same parameters for the ADSL router and all your wireless clients. Parameter WEP Mode Key Entry Method Key Provisioning Description Select 64 bit or 128 bit key to use for encryption. Select Hex or ASCII to use for encryption key Select Static if there is only one fixed key for encryption. If you want to select Dynamic, you would need to enable 802.1X function first. When the key entry method is set to Hex, you can automatically generate encryption keys using the passphrase or manually enter the keys. To generate the keys using passphrase, check the box, enter a string of text, and click GENERATE. Select the default key from the drop-down menu and click SAVE SETTINGS. 4-29 CONFIGURING THE ADSL ROUTER Before saving settings the key is shown in clear text. If your wireless client does not have a passphrase utility, make a note of the default key before saving settings. This is so you can configure your wireless client with the correct key. To manually configure the encryption key, enter five hexadecimal pairs of digits for each 64-bit key, or enter 13 pairs for the single 128-bit key.

(A hexadecimal digit is a number or letter in the range 0-9 or A-F.) Note that WEP protects data transmitted between wireless nodes, but does not protect any transmissions over your wired network or over the Internet. Note:

The passphrase can consist of up to 32 alphanumeric characters. 4-30 ADVANCED SETUP WPA Wi-Fi Protected Access (WPA) combines temporal key integrity protocol

(TKIP) and 802.1X mechanisms. It provides dynamic key encryption and 802.1X authentication service. Parameter Cypher suite Authentication Pre-shared key type Pre-shared Key Group Key Re_Keying Description TKIP is the security mechanism used in WPA for encryption. Pre-shared key: for the SOHO network environment without an authentication server. Select the key type to be used in the Pre-shared Key. Type in the key here. The period of renewing broadcast/multicast key. 4-31 CONFIGURING THE ADSL ROUTER NAT Network Address Translation allows multiple users to access the Internet sharing one public IP. Enable or disable NAT module function: select to turn on/turn off this function. 4-32 ADVANCED SETUP Address Mapping Allows one or more public IP addresses to be shared by multiple internal users. This also hides the internal network for increased privacy and security. Enter the Public IP address you wish to share into the Global IP field. Enter a range of internal IPs that will share the global IP into the from field. 4-33 CONFIGURING THE ADSL ROUTER Virtual Server If you configure the ADSL router as a virtual server, remote users accessing services such as web or FTP at your local site via public IP addresses can be automatically redirected to local servers configured with private IP addresses. In other words, depending on the requested service

(TCP/UDP port number), the ADSL router redirects the external service request to the appropriate server (located at another internal IP address). For example, if you set Type/Public Port to TCP/80 (HTTP or web) and the Private IP/Port to 192.168.2.2/80, then all HTTP requests from outside users will be transferred to 192.168.2.2 on port 80. Therefore, by just entering the IP address provided by the ISP, Internet users can access the service they need at the local address to which you redirect them. The more common TCP service ports include:

HTTP: 80, FTP: 21, Telnet: 23, and POP3: 110. A list of ports is maintained at the following link:

http://www.iana.org/assignments/port-numbers. 4-34 ADVANCED SETUP Special Application Some applications require multiple connections, such as Internet gaming, video-conferencing, and Internet telephony. These applications may not work when Network Address Translation (NAT) is enabled. If you need to run applications that require multiple connections, use these screens to specify the additional public ports to be opened for each application. 4-35 CONFIGURING THE ADSL ROUTER NAT Mapping Table This screen displays the current NAPT (Network Address Port Translation) address mappings. 4-36 ADVANCED SETUP Routing These screens define routing related parameters, including static routes and RIP (Routing Information Protocol) parameters. Static Route Parameter Index Network Address Subnet Mask Gateway Description Check the box of the route you wish to delete or modify. Enter the IP address of the remote computer for which to set a static route. Enter the subnet mask of the remote network for which to set a static route. Enter the WAN IP address of the gateway to the remote network. Click Add to add a new static route to the list, or check the box of an already entered route and click Modify. Clicking Delete will remove an entry from the list. 4-37 CONFIGURING THE ADSL ROUTER RIP RIP sends routing-update messages at regular intervals and when the network topology changes. When a router receives a routing update that includes changes to an entry, it updates its routing table to reflect the new route. RIP routers maintain only the best route to a destination. After updating its routing table, the router immediately begins transmitting routing updates to inform other network routers of the change. Parameter General RIP Parameters RIP mode Auto summary Description Globally enables or disables RIP. If Auto summary is disabled, then RIP packets will include sub-network information from all sub-

networks connected to the router. If enabled, this sub-network information will be summarized to one piece of information covering all sub-networks. Table of current Interface RIP parameter Interface The WAN interface to be configured. 4-38 Parameter Operation Mode Version Poison Reverse Authentication Required ADVANCED SETUP Description Disable: RIP disabled on this interface. Enable: RIP enabled on this interface. Silent: Listens for route broadcasts and updates its route table. It does not participate in sending route broadcasts. Sets the RIP (Routing Information Protocol) version to use on this interface. A method for preventing loops that would cause endless retransmission of data traffic. None: No authentication. Password: A password authentication key is included in the packet. If this does not match what is expected, the packet will be discarded. This method provides very little security as it is possible to learn the authentication key by watching RIP packets. MD5: An algorithm that is used to verify data integrity through the creation of a 128-bit message digest from data input (which may be a message of any length) that is claimed to be as unique to that specific data as a fingerprint is to a specific individual. Authentication Code Password or MD5 Authentication key. 4-39 CONFIGURING THE ADSL ROUTER Routing Table Parameter Description Flags Network Address Netmask Gateway Interface Metric Indicates the route status:

C = Direct connection on the same subnet. S = Static route. R = RIP (Routing Information Protocol) assigned route. I = ICMP (Internet Control Message Protocol) Redirect route. Destination IP address. The subnetwork associated with the destination. This is a template that identifies the address bits in the destination address used for routing to specific subnets. Each bit that corresponds to a 1 is part of the subnet mask number; each bit that corresponds to 0 is part of the host number. The IP address of the router at the next hop to which frames are forwarded. The local interface through which the next hop of this route is reached. When a router receives a routing update that contains a new or changed destination network entry, the router adds 1 to the metric value indicated in the update and enters the network in the routing table. 4-40 ADVANCED SETUP Firewall The ADSL routers firewall inspects packets at the application layer, maintains TCP and UDP session information including time-outs and the number of active sessions, and provides the ability to detect and prevent certain types of network attacks. Network attacks that deny access to a network device are called Denial-of-Service (DoS) attacks. DoS attacks are aimed at devices and networks with a connection to the Internet. Their goal is not to steal information, but to disable a device or network so users no longer have access to network resources. The ADSL router protects against the following DoS attacks: IP Spoofing, Land Attack, Ping of Death, IP with zero length, Smurf Attack, UDP port loopback, Snork Attack, TCP null scan, and TCP SYN flooding.

(For details see page 4-48.) The firewall does not significantly affect system performance, so we advise leaving it enabled to protect your network. Select Enable and click the SAVE SETTINGS button to open the Firewall submenus. 4-41 CONFIGURING THE ADSL ROUTER Access Control Access Control allows users to define the outgoing traffic permitted or not-permitted through the WAN interface. Parameter Enable Filtering Function Normal Filtering Table Description Click Yes to turn on the filtering function. Displays a summary of the filtering rules configured. 4-42 ADVANCED SETUP To add the PC to the filtering table:

1. Click Add PC on the Access Control screen. 2. Define the appropriate settings for client PC services. 3. Click OK and then click SAVE SETTINGS to save your settings. 4-43 CONFIGURING THE ADSL ROUTER MAC Filter The ADSL router can also limit the access of hosts within the local area network (LAN). The MAC Filtering Table allows the ADSL router to enter up to 32 MAC addresses that are not allowed access to the WAN port. Please note that this filter only applies to ethernet clients. Click Yes to enable, or No to disable this function. Enter the MAC address in the space provided. 4-44 ADVANCED SETUP URL Blocking The ADSL router allows the user to block access to web sites by entering either a full URL address or just a keyword. This feature can be used to protect children from accessing violent or pornographic web sites. You can define up to 30 sites here. 4-45 CONFIGURING THE ADSL ROUTER Time Scheduling Rule You may filter Internet access for local clients based on rules. Each access control rule may be activated at a scheduled time. Define the schedule on the Time Scheduling Rule screen, and apply the rule on the Access Control screen. 4-46 ADVANCED SETUP Follow these steps to add a schedule rule:

1. Click Add Scheduling Rule on the Time schedule rule screen. 2. Define the appropriate settings for a schedule rule. 3. Click OK and then click SAVE SETTINGS to save your settings. 4-47 CONFIGURING THE ADSL ROUTER Intrusion Detection Intrusion Detection Feature Stateful Packet Inspection (SPI) and Anti-DoS firewall protection

(Default: enabled) The Intrusion Detection Feature of the ADSL router limits access for incoming traffic at the WAN port. When the SPI feature is turned on, all incoming packets will be blocked except for those types marked in the Stateful Packet Inspection section. RIP Defect (Default: disabled) If an RIP request packet is not acknowledged to by the router, it will stay in the input queue and not be released. Accumulated packets could cause the input queue to fill, causing severe problems for all protocols. Enabling this feature prevents the packets from accumulating. Discard Ping to WAN (Default: disabled) Prevent a ping on the WAN port of the ADSL router from being routed to the network. Scroll down to view more information. 4-48 ADVANCED SETUP 4-49 CONFIGURING THE ADSL ROUTER Stateful Packet Inspection This is called a stateful packet inspection because it examines the contents of the packet to determine the state of the communications; i.e., it ensures that the stated destination computer has previously requested the current communication. This is a way of ensuring that all communications are initiated by the recipient computer and are taking place only with sources that are known and trusted from previous interactions. In addition to being more rigorous in their inspection of packets, stateful inspection firewalls also close off ports until connection to the specific port is requested. When particular types of traffic are checked, only the particular type of traffic initiated from the internal LAN will be allowed. For example, if the user only checks FTP Service in the Stateful Packet Inspection section, all incoming traffic will be blocked except for FTP connections initiated from the local LAN. Stateful Packet Inspection allows you to select different application types that are using dynamic port numbers. If you wish to use the Stateful Packet Inspection (SPI) to block packets, click on the Yes radio button in the Enable SPI and Anti-DoS firewall protection field and then check the inspection type that you need, such as Packet Fragmentation, TCP Connection, UDP Session, FTP Service, H.323 Service, or TFTP Service. When hackers attempt to enter your network, we can alert you by e-mail Enter your email address. Specify your SMTP and POP3 servers, user name, and password. 4-50 ADVANCED SETUP Connection Policy Enter the appropriate values for TCP/UDP sessions as described in the following table. Parameter Fragmentation half-open wait Defaults Description 10 sec TCP SYN wait 30 sec TCP FIN wait 5 sec TCP connection idle timeout UDP session idle timeout H.323 data channel idle timeout 3600 seconds

(1 hour) 30 sec 180 sec Configures the number of seconds that a packet state structure remains active. When the timeout value expires, the router drops the unassembled packet, freeing that structure for use by another packet. Defines how long the software will wait for a TCP session to synchronize before dropping the session. Specifies how long a TCP session will be maintained after the firewall detects a FIN packet. The length of time for which a TCP session will be managed if there is no activity. The length of time for which a UDP session will be managed if there is no activity. The length of time for which an H.323 session will be managed if there is no activity. 4-51 CONFIGURING THE ADSL ROUTER DoS Criteria and Port Scan Criteria Set up DoS and port scan criteria in the spaces provided (as shown below). Parameter Total incomplete TCP/UDP sessions HIGH Total incomplete TCP/UDP sessions LOW Incomplete TCP/UDP sessions

(per min) HIGH Incomplete TCP/UDP sessions

Defines the rate of new unestablished sessions that will cause the software to stop deleting half-

open sessions. Maximum number of allowed incomplete TCP/UDP sessions per minute. 250 sessions 250 sessions 200 sessions Minimum number of allowed incomplete TCP/UDP sessions per minute. 10 300 msec 30 10000 msec 300 second Maximum number of incomplete TCP/UDP sessions from the same host. Length of time before an incomplete TCP/UDP session is detected as incomplete. Maximum number of half-open fragmentation packets from the same host. Length of time before a half-open fragmentation session is detected as half-open. Length of time from detecting a flood attack to blocking the attack. Note: The firewall does not significantly affect system performance, so we advise enabling the prevention features, and leaving them at the default settings to protect your network. 4-52 ADVANCED SETUP DMZ If you have a client PC that cannot run an Internet application properly from behind the firewall, you can open the client up to unrestricted two-way Internet access. Enter the IP address of a DMZ (Demilitarized Zone) host on this screen. Adding a client to the DMZ may expose your local network to a variety of security risks, so only use this option as a last resort. 4-53 CONFIGURING THE ADSL ROUTER UPnP The Universal Plug and Play architecture offers pervasive peer-to-peer network connectivity of PCs of all form factors, intelligent appliances, and wireless devices. UPnP enables seamless proximity network in addition to control and data transfer among networked devices in the office, home and everywhere within your network. UPnP allows the device to automatically:

join a network obtain an IP address convey its capabilities and learn about the presence and capabilities of other devices. Check the Enable option to activate the function. 4-54 ADVANCED SETUP QoS The QoS (Quality of Service) function allows you to differentiate traffic types and provide high-priority forwarding service for applications such as VoIP or gaming. Parameter Enable or disable QoS module function Diffserv Forwarding Groups Description Check to enable or disable this function. BE AF1x AF2x AF3x AF4x EF Best Effort forwarding, set the percentage for this type od Qos. Set the percentage for four different types of Assured Forwarding. Expedited Forwarding, is intended to provide low delay, low jitter and low loss delivery of packets. 4-55 CONFIGURING THE ADSL ROUTER Traffic Mapping Use this screen to classify traffic into Diffserv forwarding groups and outgoing VCs. Click Add traffic class to add a new rule for traffic class. 4-56 ADVANCED SETUP Traffic Statistics This screen shows the WAN outbound traffic statistics of all the Diffserv forwarding groups in the last 12 hours. Click Refresh to renew the list. 4-57 CONFIGURING THE ADSL ROUTER DDNS Dynamic Domain Name Service (DDNS) provides users on the Internet with a method to tie their domain name to a computer or server. DDNS allows your domain name to follow your IP address automatically by having your DNS records changed when your IP address changes. This DDNS feature is powered by:

DynDNS.org TZO.com With a DDNS connection you can host your own web site, email server, FTP site, and more at your own location even if you have a dynamic IP address. 4-58 ADVANCED SETUP Tools Use the Tools menu to backup the current configuration, restore a previously saved configuration, restore factory settings, update firmware, and reset the ADSL router. Configuration Tools Backup allows you to save the ADSL routers configuration to a file. Restore can be used to restore the previously saved backup configuration file.

The ADSL router can be easily monitored through panel indicators to identify problems. Troubleshooting Chart Symptom LED Indicators Power LED is Off Action Check connections between the ADSL router, the external power supply, and the wall outlet. If the power indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or external power supply. However, if the unit powers off after running for a while, check for loose power connections, power losses, or surges at the power outlet. If you still cannot isolate the problem, then the external power supply may be defective. In this case, contact Technical Support for assistance. A-1 TROUBLESHOOTING Troubleshooting Chart Symptom LED Indicators Link LED is Off Action Verify that the ADSL router and attached device are powered on. Be sure the cable is plugged into both the ADSL router and the corresponding device. Network Connection Problems Cannot ping the ADSL router from the attached LAN Verify that the proper cable type is used and that its length does not exceed the specified limits. Be sure that the network interface on the attached device is configured for the proper communication speed and duplex mode. Check the adapter on the attached device and cable connections for possible defects. Replace any defective adapter or cable if necessary. Verify that the IP addresses are properly configured. For most applications, you should use the ADSL routers DHCP function to dynamically assign IP addresses to hosts on the attached LAN. However, if you manually configure IP addresses on the LAN, verify that the same network address (network component of the IP address) and subnet mask are used for both the ADSL router and any attached LAN devices. Be sure the device you want to ping (or from which you are pinging) has been configured for TCP/IP. A-2 TROUBLESHOOTING Troubleshooting Chart Action Symptom Management Problems Cannot connect using the web browser Forgot or lost the password Be sure to have configured the ADSL router with a valid IP address, subnet mask, and default gateway. Check that you have a valid network connection to the ADSL router and that the port you are using has not been disabled. Check the network cabling between the management station and the ADSL router. Press the Reset button on the rear panel (holding it down for at least five seconds) to restore the factory defaults. A-3 TROUBLESHOOTING Troubleshooting Chart Symptom Wireless Problems A wireless PC cannot associate with the ADSL router. The wireless network is often interrupted. The ADSL router cannot be detected by a wireless client. Action Make sure the wireless PC has the same SSID settings as the ADSL router. See Channel and SSID on page 4-26. You need to have the same security settings on the clients and the ADSL router. See Security on page 4-28. Move your wireless PC closer to the ADSL router to find a better signal. If the signal is still weak, change the angle of the antenna. There may be interference, possibly caused by a microwave ovens or wireless phones. Change the location of the interference sources or of the ADSL router. Change the wireless channel on the ADSL router. See Channel and SSID on page 4-26. Check that the antenna, connectors, and cabling are firmly connected. The distance between the ADSL router and wireless PC is too great. Make sure the wireless PC has the same SSID and security settings as the ADSL router. See ADSL router. See Channel and SSID on page 4-26 and Security on page 4-28.
