4. 7.  Forwarding
The router’s NAT (Network Address Translation) feature makes the devices on 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 hosts cannot initiatively communicate with the specified devices 
in the local network.
With the forwarding feature, the router can traverse the isolation of NAT so that clients 
on the Internet can reach devices on the LAN and realize some specific functions.
The 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.
4. 7. 1.  Virtual Servers
When you build up a server in the local network and want to share it on the Internet, 
Virtual Servers can realize the service and provide it to Internet users. At the same time 
virtual servers can keep the local network safe as other services are still invisible from 
the Internet.
Virtual Servers can be used to set up public services in your local network, such as HTTP, 
FTP, DNS, POP3/SMTP and Telnet. Different service uses different service port. Port 80 
is used in HTTP service, port 21 in FTP service, port 25 in SMTP service and port 110 in 
POP3 service. Please verify the service port number before the configuration.
