Firewall & Dmz - D-Link DSL-2640B User Manual

Section 4 - Troubleshooting
FIREWALL & DMZ
The Firewall & DMZ window allows the Router to enforce specific predefined policies intended to protect against certain common types of attacks.
There are two general types of protection (DoS, Port Scan) that can be enabled on the Router, as well as filtering for specific packet types
sometimes used by hackers.
Since some applications are not compatible with NAT, the Router supports use of a DMZ IP address for a single host on the LAN. This IP address is
not protected by NAT and will therefore be visible to agents on the Internet with the right type of software. Keep in mind that any client PC in the
DMZ will be exposed to various types of security risks. If you use the DMZ, take measures (such as client-based virus protection) to protect the
remaining client PCs on your LAN from possible contamination through the DMZ.
To access the FIREWALL & DMZ setting window, click on the Firewall & DMZ button under the ADVANCED tab.
