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.
