Hi all,
So I have a really weird issue with one of my Wireguard tunnels.
I have a VPS with a static IP with Hetzner, SMTP traffic is allowed by Hetzner, the VPS runs on Pfsense (latest version) and is up and running.
At home I have my Proxmox homelab server and my physical firewall with Opnsense (latest version).
A tunnel exists between Hetzner and my home, and I can see in the logs that for exampel http(s) and snmp traffic is going over it nicely.
Now when I try to send over SMTP traffic it goes through the tunnel, but it never arrives on my Opnsense firewall.
Same goes for different ports, all except 80, 161, 443 seems to be working.
Literally nothing is in the logs.
I am going nuts over troubleshooting this and can't seem to pinpoint the origin of the issue.
