NAT Forwarding
The router's NAT (Network Address Translation) feature means devices on a local
network use the same public IP address to communicate with devices on the Internet,
which protects local hosts by hiding their IP addresses. However, it also brings about
a problem in that an external host cannot communicate with devices on the local
network. With the forwarding feature, the router can allow external hosts on the
Internet to reach local network devices.
The TP-LINK router supports 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.
It 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
