particular range of service port numbers (from the
Internet/WAN Ports) to a particular LAN IP address.
You can have different services (e.g. email, FTP, Web
etc.) going to different service servers/clients in your
LAN. The Virtual Server allows you to re-direct a
particular service port number (from the Internet/WAN
Port) to a particular LAN IP address and its service port
number.
Some applications require multiple connections, such as
Internet games, video conferencing, Internet telephony
and others. In this section you can configure the router

It allows to Enable or Disable UPnP feature here. After
you enable the UPnP feature, all client systems that
support UPnP, like Windows XP, can discover this router
automatically and access the Internet through this router
without any configuration. The NAT Traversal function
provided by UPnP can let applications that support
UPnP smoothly connect to Internet sites without any
incompatibility problem due to the NAPT port translation.
You can select special
"Application Layer Gateway" to support here.
You can disable NAT function and setup the routing
rules manually.
