As mentioned above, Port Redirection can redirect incoming TCP/UDP or other traffic on
particular ports to the specific private IP address/port of host in the LAN. However, other IP
protocols, for example Protocols 50 (ESP) and 51 (AH), do not travel on a fixed port. Vigor
router provides a facility DMZ Host that maps ALL unsolicited data on any protocol to a single
host in the LAN. Regular web surfing and other such Internet activities from other clients will
continue to work without inappropriate interruption. DMZ Host allows a defined internal user
to be totally exposed to the Internet, which usually helps some special applications such as
Netmeeting or Internet Games etc.
The security properties of NAT are somewhat bypassed if you set up DMZ host. We suggest
you to add additional filter rules or a secondary firewall.
Click DMZ Host to open the following page. You can set different DMZ host for each WAN
interface. Click the WAN tab to switch into the configuration page for that WAN.
