So my friend and I are able to enable UPnP and in the network menu in plutonium UPnP shows up as enabled, but for my other friend it shows up as disabled and his IP address is set to 0.0.0.0. He was also unable to host a custom game even after enabling port forwarding through his router.
We have tried uninstalling a network driver that might have caused some conflict, enabling UPnP through his router, enabling port forwarding, and even tried using utorrent to enable UPnP on port 4976.
There are no errors that show up on the screen.
Any solutions to these issues?
