Chapter 9 NAT Forwarding Router's NAT (Network Address Translation) feature makes the devices in the LAN use the same public IP address to communicate on the Internet, which protects the local network by hiding IP addresses of the devices. However, it also brings about the problem that external host cannot initiatively communicate with the specified device in the local network. With forwarding feature the router can penetrate the isolation of NAT and allows the external hosts on the Internet to initiatively communicate with the devices in the local network, thus to realize some special functions. TP-LINK router includes four forwarding rules. If two or more rules are set, the priority of implementation from high to low is Virtual Servers, Port Triggering, UPNP and DMZ. This chapter contains the following sections: • Share Local Resources on the Internet by Virtual Servers • Open Ports Dynamically by Port Triggering • Make Applications Free from Port Restriction by DMZ • Make Xbox Online Games Run Smoothly by UPnP

NAT Forwarding
Router’s NAT (Network Address Translation) feature makes the devices in the LAN
use the same public IP address to communicate on the Internet, which protects the
local network by hiding IP addresses of the devices. However, it also brings about the
problem that external host cannot initiatively communicate with the specified device
in the local network.
With forwarding feature the router can penetrate the isolation of NAT and allows the
external hosts on the Internet to initiatively communicate with the devices in the local
network, thus to realize some special functions.
TP-LINK router includes four forwarding rules. If two or more rules are set, the priority
of implementation from high to low is Virtual Servers, Port Triggering, UPNP and DMZ.
