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.
