Warcraft 2 (GOG) Multiplayer Issues

Hi there. I am running into the whole internet processing unable to forward udp packets issue. I am wondering if it is just not possible to run on public wifi? That would hurt because I am rarely home and my home internet is crazy slow. Wanted to add a screenshot, but I wasn’t able to find the option to do that

I’m not sure if you can play on public WiFi. Unless it’s maybe Starbucks… in which case you would most likely have to hole punch the server you are playing on.
