Port Forwarding Setup
(NF5)

Port Forwarding
Port forwarding enables programs or devices running on your LAN to communicate with the
internet as if they were directly connected.
This is most commonly used for VOIP ATA devices or online gaming (via game console or
computer).
Port forwarding works by “forwarding” a specific TCP or UDP port from the router to the
computer or device you are using.
You can also restrict which incoming connections will have the rule applied to it. This enables
you to specify all incoming connections, from a specific subnet or from an individual IP
address.*
Different services and different games all use different TCP or UDP ports.
You will need to consult any information supplied with your service or game in
order to find which ports need to be forwarded.
You can only forward a port to one location (IP address).
In some cases, this may cause issues when multiple LAN devices (computers,
game consoles, or VOIP ATAs) attempt to use online gaming as same time or
make multiple VOIP service connections.
In these cases, you would need to use an alternate port for any subsequent
connections after the first device.
Please consult your VOIP provider or game manufacturer for assistance with this.
* - If supported by your model of router.

Adding a Port Forwarding Rule
This guide will take you through the steps required to add a port forwarding rule to your
router.
1. Navigate to http://192.168.20.1 in a web browser.
2. Enter “admin” (without quotes) as both the username and password and press the
Login button.
3. If you have been asked for First Time Setup Wizard , choose “No Thanks, take me to
the Basic Interface.”

4. Select the “Switch to Advanced View” option from near the bottom of the screen.
5. Select the Port Forwarding option from the Forwarding Rules menu.
6. Enter the port number that you wish to port forward to into the Service Ports field.
7. Enter the IP address of the device you wish to port forward data to in the Server IP
field.
8. Enter a tick to Enable the port forwarding rule and set the Use Rule option to
Always.
9. Press the Save button at the bottom of the page to Save the port forwarding rule.

Please note: Some services require more than one port forwarded. You can do this by
specifying a sequential range of ports instead of just one.
For example: 6881-6999.
You can only forward a port to one location (IP address).
In some cases, this may cause issues when multiple LAN devices (computers,
game consoles, or VOIP ATAs) attempt to use online gaming as same time or
make multiple VOIP service connections.
In these cases, you would need to use an alternate port for any subsequent
connections after the first device.
Please consult your VOIP provider or game manufacturer for assistance with this.
