How to
Set up port forwarding
You can open and forward the router ports to a computer or game console on your local network. Remember, you need to know the IP address of the device you want to forward the ports to and establish a connection to the router web interface. To use this function, you must have a static IP address. Contact Optus customer service for more information on how to obtain a static IP address.
