Hi, i'm new here, nice to meet you all. I'm having a bit of difficulty setting up my server. It's the first time i'm setting up a wow server, i only know how to set up a minecraft one. In particular i'm finding hard to understand wich ports i have to open to let it run without unwanted connections or access on my network. My build is 1.12 and at the moment i have a lot of ports open to let it work but i really cannot understand wich are truly necessary . Can someone help me pls, here is a photo of all the ports, i also need to know wich are to open for inbound and wich for outbound. sorry for my bad english.
