Wireguard blocks ssh/smb :(

www.digitalocean.com /community/tutorials/how-to-set-up-wireguard-on-ubuntu-22-04

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.
