Nat Forwarding - TP-Link Touch P5 User Manual

NAT Forwarding

2.22
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 in 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.
