:4013 is a port you'd like to listen on for incoming connections

:25565, :25566 are downstream servers, if multiple addresses are provided traffic will be load balanced between servers (round robin)

proxy := glowstone.NewProxy(":4013", ":25565", ":25566")
proxy.Listen()

Add new server

Your server should be visible and repspond to client's healthchecks

If your downstream servers are reachable, you should be able to play 🍾
