Advanced DMZ Host Page
This page allows you to specify the "default" recipient of WAN traffic that NAT is unable to
translate to a known local PC. The DMZ (De-militarized Zone) hosting (also commonly referred to
as "Exposed Host") can also be described as a computer or small sub-network that sits between
the trusted internal private LAN and the untrusted public Internet.
Figure 43 Advanced DMZ Host Page
You may configure one PC to be the DMZ host. This setting is generally used for PCs using
"problem" applications that use random port numbers and do not function correctly with specific
port triggers or the port forwarding setups mentioned earlier. If a specific PC is set as a DMZ
Host, remember to set this back to "0" when you are finished with the needed application, since
this PC will be effectively exposed to the public Internet, though still protected from Denial of
Service (DoS) attacks via the Firewall.
Setting Up the DMZ Host
1. Enter the computer’s IP address.
2. Click Apply to activate the selected computer as the DMZ host.
