For example, the built-in Web User Interface in the modem is with default port 80, which
may conflict with the web server in the local network, http://192.168.1.13:80. Therefore, you
need to
change the modem’s http port to any one other than the default port 80 to avoid
conflict, such as 8080. This can be set in the System Maintenance >>Management Setup .
You then will access the admin screen of by suffixing the IP address with 8080, e.g.,

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
modem 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.
