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. 
 
Note: 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.
