Chapter 10

NAT Forwarding

Router’s NAT (Network Address Translation) feature makes the devices in the LAN

use the same public IP address to communicate in 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 in the Internet by Virtual Server

• Open Ports Dynamically by Port Triggering

• Make Applications Free from Port Restriction by DMZ

• Make Xbox Online Games Run Smoothly by UPnP
