Ericsson W3X manual Application Server Port, Port Forwarding Example

Configuration and Management

Figure 38 - Add Port forwarding Instance page

Select a “Protocol” from the drop-down list and type the appropriate values in “NAT Port”, “Server IP”, and “Server Port” fields and click Apply to save 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.

Table 19 - Common applications server ports

Application	Server Port
MSN Messenger®	6901
Unreal Tournament 2004®	7777, 7778, 7787, 28902
NetMeeting®	1720, 1503
Quake III®	27669 (+1 for each player)

Note: If multiple ports or port ranges are required, create a new port entry for each port or port range.

3.7.3.2Port 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.
