Chapter 11  

NAT Forwarding  

Modem 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.  

The modem router can use a forwarding feature to remove the isolation of NAT and  

allow external internet hosts to intuitively communicate with the devices in the local  

network, thus enabling some special features.  

TP-Link modem 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:  

• Translate Address and Port by ALG  

• Share Local Resources over 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
