4.9.1 Virtual servers
There are four submenus under the
Forwarding
menu (shown in Figure 4-27):
Virtual Servers
,
Port Triggering
,
DMZ
and
UPnP
. Click any of them to be able to configure the corresponding
function. Detailed descriptions of each submenu are provided in the sections 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 is used as
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 to gain access to certain applications such as Internet gaming or
videoconferencing. DMZ host forwards all the ports at the same time. Any PC with a port 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.
