Ew, is it really getting that bad?

I've been setting up dedicated game servers and networking ♥♥♥♥ for years, I only heard people talking ambiguously about "Running out of IP addresses" but I lived through Y2K, so I just immediately dismissed it as another way to sell old bottled water.

Idk really, only have own limited experiance, but where i live (poland) some BIG isps are doing NAT with no way out. Previously you could buy yourself out at one time fee at least, and even earlier NATs were only on wifi rural internets. I got lucky with fiber that offers external IP still but its not cheap.

Yeah, Im old enough to use physical dictionaries from time to time, so know the value of good documentation too. The times are moving on thou. We might not like youtube, but for some people its way easier and faster to process and apply the information in that form these days. And look at the OP again, hes not even using a good translator, nor has idea of dedi servers, he'll barely understand basics here. Most likely chance of getting anywhere is a video guide, at least IMHO.

I do appreciate the links thou!

Junctions are great, but i'd be wary of using it online... Valheim saves can be base for few server instances (in different sessions), last one out the door gets to save. So it could happen that both friends play solo by mistake and one looses progress.
At this complexity point remote start of the server on the friends PC could work too haha.
