2 internal PCs, 1 external - how do I set this up?

[NineShadowEyes]

My situation: In my house, there's me hosting and my wife playing, and our friend connects from the internet.

Do I setup the port forwarding to my PC so my online pal can connect to me, and then just connect my wife's laptop directly to me using my internal IP?

Thanks.

You may not even need to set port forwarding if FG can set it up automatically, but essentially yes. External connections need Port 1802 open. Internal connection use your the Internal IP address of the host machine.

Give the external person your external IP or alias and your internal (wife) your internal IP.

All three are listed on the FG start screen.
