4.9 Forwarding
There are four submenus under the Forwarding menu (shown in Figure 4-27): Virtual Servers,
Port Triggering, DMZ and UPnP. Click any of them, and you will be able to configure the
corresponding function. The detailed explanations for each submenu are provided below.
Virtual servers can be used for setting up public services on your LAN, such as DNS, Email and
FTP. A virtual server is defined as a service port, and all requests from the Internet to this service
port will be redirected to the computer specified by the server IP. Any PC that was used for a
virtual server must have a static or reserved IP Address because its IP Address may change
when using the DHCP function. Port Triggering is used for some applications that cannot work
with a pure NAT router, like Internet games, video conferencing, Internet calling and so on, which
require multiple connections. The DMZ host feature allows one local host to be exposed to the
Internet for a special-purpose service such as Internet gaming or videoconferencing. DMZ host
forwards all the ports at the same time. Any PC whose port is being forwarded must have its
DHCP client function disabled and should have a new static IP Address assigned to it because its
IP Address may change when using the DHCP function. The Universal Plug and Play (UPnP)
feature allows the devices, such as Internet computers, to access the local host resources or
devices as needed. UPnP devices can be automatically discovered by the UPnP service
application on the LAN.
