Remote Access over the internet

[HaloJones]

Port forwarding usually works on the target end. On your Dad's router you would tell it that an incoming call on the public IP and port 36330 should go to the private IP of your Dad's computer.

So, your Dad's public IP is x.x.x.x and his internal network IP is 192.168.0.2, on your Dad's router you set up port forwarding for x.x.x.x:36330 to go to 192.168.0.2:36330
