8-12 Advanced Configuration of the Router

202-10072-01, March 2005

If disabled, you must connect manually, using the “Connection Status” button on the Router Status

screen. This manual connection will stay up all the time without time outs.

Disabling the SPI Firewall

The SPI (Stateful Inspection) Firewall protects your LAN against Denial of Service attacks. This

should only be disabled in special circumstances.

Setting Up a Default DMZ Server

The default DMZ server feature is helpful when using some online games and videoconferencing

applications that are incompatible with NAT. The router is programmed to recognize some of these

applications and to work properly with them, but there are other applications that may not function

well. In some cases, one local computer can run the application properly if that computer’s IP

address is entered as the default DMZ server.

Incoming traffic from the Internet is normally discarded by the router unless the traffic is a

response to one of your local computers or a service that you have configured in the Ports menu.

Instead of discarding this traffic, you can have it forwarded to one computer on your network. This

computer is called the Default DMZ Server.

The WAN Setup menu, shown below lets you configure a Default DMZ Server.

To assign a computer or server to be a Default DMZ server, follow these steps:

1. Click WAN Setup link on the Advanced section of the main menu.

2. Type the IP address for that server. To remove the default DMZ server, replace the IP address

numbers with all zeros.

3. Click Apply.

Responding to Ping on Internet WAN Port

If you want the router to respond to a 'ping' from the Internet, click the ‘Respond to Ping on

Internet WAN Port’ check box. This should only be used as a diagnostic tool, since it allows your

router to be discovered. Don't check this box unless you have a specific reason to do so.

Note: DMZ servers pose a security risk. A computer designated as the default DMZ

server loses much of the protection of the firewall, and is exposed to exploits from the

Internet. If compromised, the DMZ server can be used to attack your network.
