Using the Conguration Menu (continued) Advanced > Virtual Server continued Click on this icon to edit the virtual service Click on this icon to delete the virtual service Example #2:
If you have an FTP server that you wanted Internet users to access by WAN port 2100 and only during the weekends, you would need to enable it as such. FTP server is on LAN computer 192.168.0.30. FTP uses port 21, TCP. Name: FTP Server Private IP: 192.168.0.30 Protocol Type: TCP Private Port: 21 Public Port: 2100 Schedule: From: 01:00AM to 01:00AM, Sat to Sun All Internet users who want to access this FTP Server must connect to it from port 2100. This is an example of port redirection and can be useful in cases where there are many of the same servers on the LAN network. 21 Using the Conguration Menu (continued) Advanced > Applications Some applications require multiple connections, such as Internet gaming, video conferencing, Internet telephony and others. These applications have difculties working through NAT (Network Address Translation). Special Applications makes some of these applications work with the DI-524. If you need to run applications that require multiple connections, specify the port normally associated with an application in the Trigger Port eld, select the protocol type as TCP or UDP, then enter the public ports associated with the trigger port to open them for inbound trafc. The DI-524 provides some predened applications in the table on the bottom of the web page. Select the application you want to use and enable it. Note! Only one PC can use each Special Application tunnel. Name:
Trigger Port:
This is the name referencing the special application. This is the port used to trigger the application. It can be either a single port or a range of ports. This is the protocol used to trigger the special application. Trigger Type:
Public Port:
Public Type:
This is the port number on the WAN side that will be used to access the application. You may dene a single port or a range of ports. You can use a comma to add multiple ports or port ranges. This is the protocol used for the special application. 22 Using the Conguration Menu (continued) Advanced > Filters > IP Filters Filters are used to deny or allow LAN (Local Area Network) computers from accessing the Internet. The DI-524 can be setup to deny internal computers by their IP or MAC addresses. The DI-524 can also block users from accessing restricted web sites. IP Filters:
IP Filter is used to deny LAN IP addresses from accessing the Internet. You can deny specic port numbers or all ports for the specic IP address. The IP address of the LAN computer that will be denied access to the Internet. The single port or port range that will be denied access to the Internet. Select the protocol type This is the schedule of time when the IP Filter will be enabled. IP Address:

23 Using the Conguration Menu (continued) Advanced > Filters > URL Blocking URL Blocking is used to deny LAN computers from accessing specic web sites by the URL. A URL is a specially formatted text string that denes a location on the Internet. If any part of the URL contains the blocked word, the site will not be accessible and the web page will not display. To use this feature, enter the text string to be blocked and click Apply. The text to be blocked will appear in the list. To delete the text, just highlight it and click Delete. Filters-

(continued) Use MAC (Media Access Control) Filters to allow or deny LAN (Local Area Network) computers by their MAC addresses from accessing the Network. You can either manually add a MAC address or select the MAC address from the list of clients that are currently connected to the Broadband Router. Filters-

Select a DHCP client from the pull-down list; click Clone to copy that MAC Address. Enter the MAC Address. 25 Using the Conguration Menu Advanced > Filters > Domain Blocking
(continued) Domain Blocking is used to allow or deny LAN (Local Area Network) computers from accessing specic domains on the Internet. Domain blocking will deny all requests to a specic domain such as http and ftp. It can also allow computers to access specic sites and deny all other sites. Filters-

It works in the same way as IP Filters with additional settings. You can create more detailed access rules for the DI-524. When virtual services are created and enabled, it will also display in Firewall Rules. Firewall Rules contain all network rewall rules pertaining to IP (Internet Protocol). In the Firewall Rules List at the bottom of the screen, the priorities of the rules are from top (highest priority) to bottom (lowest priority.) Enable or disable the Firewall Enter the name Note:
The DI-524 MAC Address ltering rules have precedence over the Firewall Rules. Firewall Rules-

Enter your DDNS account host name. Username/Email- Enter your DDNS account username. Password/Key-
Enter your DDNS account password. 28 Using the Conguration Menu (continued) Advanced > DMZ If you have a client PC that cannot run Internet applications properly from behind the DI-
524, then you can set the client up for unrestricted Internet access. It allows a computer to be exposed to the Internet. This feature is useful for gaming purposes. Enter the IP address of the internal computer that will be the DMZ host. Adding a client to the DMZ
(Demilitarized Zone) may expose your local network to a variety of security risks, so only use this option as a last resort. DMZ-
Enable or Disable the DMZ. The DMZ (Demilitarized Zone) allows a single computer to be exposed to the internet. By default the DMZ is disabled. IP Address-

SSID Broadcast-
Beacons are packets sent by an Access Point to synchronize a wireless network. Specify a value. 100 is the default setting and is recommended. This value should remain at its default setting of 2432. If incon-
sistent data ow is a problem, only a minor modication should be made. The fragmentation threshold, which is specied in bytes, deter-
mines whether packets will be fragmented. Packets exceeding the 2346 byte setting will be fragmented before transmis-
sion.2346 is the default setting
(Delivery Trafc Indication Message) 3 is the default setting. A DTIM is a countdown informing clients of the next window for listening to broadcast and multicast messages. Select Short or Long Preamble. The Preamble denes the length of the CRC block (Cyclic Redundancy Check is a com-
mon technique for detecting data transmission errors) for communication between the wireless router and the roaming wireless network adapters. Note: High network trafc areas should use the shorter preamble type. Auto is the default selection. Selct from the drop down menu. Choose Enabled to broadcast the SSID across the network. All devices on a network must share the same SSID (Service Set Identier) to establish communication. Choose Disabled if you do not wish to broadcast the SSID over the network. 30
