Your server comes with the one port players connect to. A few popular add-ons need a port of their own on top of that: Simple Voice Chat for in-game voice, or Geyser so Bedrock players (phone, Xbox, Switch) can join your Java world. Grab one spare per add-on — if you're not adding any, one port is all you need.
What your server will be called in the game panel. Pick anything — you can rename it later.
