Set up port forwarding

[rephil]

I have a port open 10308 to host game I also need port 5003 5002 open for voice communications (DCS simple radio server)  but it does not work . How can I set up both to be open. When I try and set it up it has an IP address that is different from the game port and it is greyed out
