On my old computer I could always port these all with no problem so I know how to do it. But I got a new computer from XP to vista so I got on to port forward my games and I did but my friend couldnt join so I checked my ports and it said they were not reachable.
Sorry for the long wait. I did some research for the games you have listed in the screenshots. One thing to try is take a quick look at this link for the required ports for games under the Steam platform and see if your friend is able to join after opening more of the recommended ports in your gateway.
If you encounter any issues with your service or equipment, I recommend checking out our Troubleshoot & Resolve solutions to help diagnose the issue.
