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.
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.
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 Port
Forwarding / Port Triggering 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 lets you configure a Default DMZ Server.
To assign a computer or server to be a Default DMZ server, follow these steps:
1. Click the WAN Setup link in the Advanced section of the main menu.
2. Type the IP address for that server and select the "Default DMZ Server" check box.
3. Click Apply.
To remove the DMZ server, perform steps 1-3 above, but clear the "Default DMZ Server"
checkbox in step 2.
