the setting.

Below are some examples of common applications and corresponding
server port they use for network access. The “NAT Port” has often the
same value as the “Server Port” value. Exceptions are made when the
same applications are used on many clients on the LAN/WLAN, where
each “Server IP” value needs to be unique and differ from the “NAT Port”
value.

Port Forwarding Example

In the following example, port forwarding is used to allow incoming access
(from the external network (Internet)) to an internal web server (on the
LAN/WLAN). The TCP protocol is used for data traffic. The NAT port 80 on
the Ericsson W3x is open and the destination computer on the LAN with
static server IP address 192.168.1.101 has appointed the server port 8080
to be used.
