thanks for the reply, but i’ve already setup a tailscale network for my group yesterday, and its working as we needed, since its usuable on mobile too.

>How many IP’s does your router have?

my router displays an ip starting with 100.X.X.X, with (dynamic) in parentheses behind it, with which my server is also reachable from within the private network. apparently this is a CGNAT? i haven’t really had to deal with this before, but reading up on it it seems to imply that the server wont be reachable, unless my ISP is going to setup port forwarding for me, which they wont do.
