I've been trying to host a server to play with my friends, but it seems that's not going to happen because I'm on CGNAT.

Is there anything I could do? Is it possible for me to use IPv6 or something else?

Sorex wdym? for it to show up on the server list?

I created a server, but when I try to connect to it from another pc on the same network, it says "Joining game session" and it gives up after a few seconds.
On Plutonium's cmd, a few attempts of connecting to the server show up, and this shows up at the top:
[DW][Lobby] Handling pubfile "largeheatmap.raw"...
But nothing else happens. What could be causing this?
