Problem Description

Issue

No matter what I do, I can’t get Game Port 2456 UDP to work! I have a CODA-4680 router I think I opened port 2456 and 2457 correctly. Port 2457 is listening. I can join my Valheim game as I’m on my server’s network but my friends cannot: they say they are ‘‘banned’’

Reproduction Steps

  • Done ampinstmgr dumpfirewall and ampinstmgr updatefirewall
  • 2456 and 2457 port forwarding
  • Add friends steam IDs to players allowed in my server
