Setting Up NAT Forwarding for a Game Server

Thomas manages a Civilization IV server on a computer behind the Device. In order for players on

the Internet (like

A

in the figure below) to communicate with the server, Thomas can use port

forwarding or application forwarding. Application forwarding can be easier to set up since you do

not need to specify port numbers manually.

Note: You cannot configure an application forwarding rule that uses the same ports as a

configured port forwarding rule.

Note: If firewall is enabled, you may also need to configure an Access Control List rule for

the relevant ports. See

Access Control List

.

Port Forwarding

Thomas needs to configure the port settings and IP address on the Device. Traffic should be

forwarded to TCP/UDP port 6500, and UDP ports 2302 and 13139 of the server computer which has

an IP address of 192.168.1.34.

Thomas may set up the port settings by configuring the port settings for the server computer.

Click

Network Settings > NAT > Add new rule

and configure the screen with the following

values:

Repeat steps 1 and 2 for UDP ports 2302 and 13139. The port forwarding settings you configured

appear in the table.

Players on the Internet then can have access to Thomas’ server.

Access Your Home Computer from the Internet Using

DDNS

If you connect your Device to the Internet and it uses a dynamic WAN IP address, it is inconvenient

for you to access your home computer from the Internet. The Device’s WAN IP address changes

dynamically. Dynamic DNS (DDNS) allows you to access your home computer using a domain

name.

Note: You will need to enable remote desktop server service on your home computer. The

remote desktop server feature is only included in Windows Professional, Business

and Ultimate versions.

Note: If firewall is enabled, you may also need to configure an Access Control List rule for

the relevant ports. See

Access Control List

.

To use this feature, you have to apply for DDNS service at www.dyndns.org.

This tutorial covers:

•

Registering a DDNS Account on www.dyndns.org

•

Configuring DDNS on Your Device

•

Configuring Port Forwarding on your Device

•

Testing the DDNS Setting

Note: If you have a private WAN IP address, then you cannot use DDNS.
