I have Ubuntu 16.04 and the others have Windows. I am not able to see their server nor are they able to see my servers. I am also not able to find any internet servers.
I am using wine to run Counter Strike 1.6
However, I am able to connect directly to the host ip and join the game. This is why it's not similar to this question
Does anyone know how to solve this issue? Has anyone faced this issue?
