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:

[Interface]
Address = 192.168.1.120/24
SaveConfig = true
PostUp = iptables -A FORWARD -i %i -j ACCEPT; iptables -t nat -A POSTROUTING -o wlp1s0 -j MASQUERADE
PostDown = iptables -D FORWARD -i %i -j ACCEPT; iptables -t nat -D POSTROUTING -o wlp1s0 -j MASQUERADE
ListenPort = 51820
PrivateKey = XXX

[Peer]
PublicKey = xxx
AllowedIPs = 192.168.1.230/32
Endpoint = 192.168.1.230:50104

No extra config was made.

      There is nothing special about the config, it’s the most basic config you can have as shown in the example at the bottom of this page.

      https://docs.opnsense.org/manual/how-tos/wireguard-client.html

      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)
