Problem Description

Issue

I tried playing on this server with my friend, but it was VERY slow. I tried tweaking some settings here and there, but I was told terraria was not optimized for TCP. So I’m trying to set it up for UPD and… it’s not listening to my UPD custom port. What can I do to make it listen? Otherwise, how can I make the connection speed acceptable?

Reproduction Steps

  • Add custom UPD Port
  • Add router port forward
  • Restart amp and game instance

Technically Terraria only opens a socket on TCP

But you can test your theory by manually creating a firewall rule for the same port for UDP, and forward that as well in your router
