In this tutorial, you will set up WireGuard on an Ubuntu 22.04 server, and then configure another machine to connect to it as a peer using both IPv4 and IPv6…
This was manually solved, I didn't check any other comment till the issue was fixed.
Take a look at my comment.
Thank you all for helping!
Hello.
I have wireguard set but the second it runs, services like ssh (22) and smb (455/445?) stop working.
nmap thinks my system is down.
Here is my config, I followed debian's guide since my server is Deb12:
The part that was a bit complex is the 'server' setting. My server is on my router (opnsense) so you need to opnsense specific settings.
I suspect the reason you need the extra stuff is because of how the Debian server is setup so that stuff will vary if you ever try to run another 'server' node. (I put server in quotes because wireguard doesn't actually have server and client as a concept)
