9. Port Forwarding
This section contains two parts: Basic and Forwarding. Port forwarding is the
forwarding of network ports from one network device to another. This is
commonly done using a NAT (network address translation) enabled router or
server and another computer within the network.

The UPnP Internet Gateway Device (IGD) is an “edge” interconnect device
between a residential Local Area Network (LAN) and the Wide Area Network
(WAN). It provides connectivity to the Internet with automatic and seamless
sharing and configuration of Internet data access among networked devices in
the residential network.
UPnP functionality also provides user with:
1 Multi-player games
2 Real time communications (such as MSN Messenger)
3 Peer-to-peer services
You have to enable Universal Plug and Play (UPnP) Internet Gateway Device
(IGD) profile to allow certain Windows applications set up the port forwarding rule
dynamically when NAT is enabled on this device.
Enable a specific LAN client allows you to accept inbound connections which do
not match with any forwarding rules and triggering rules. This client sometimes is
referred as
DMZ
(Demillitarized Zone).
Follow the steps below to set up the UPnP.
1. From the Basic web page, click
Add LAN Client
. The DMZ cannot be enabled
until the LAN client is added.
