I want to move away from Cloudflare tunnels, so I rented a cheap VPS from Hetzner and tried to follow this guide. Unfortunately, the WireGuard setup didn’t work. I’m trying to forward all traffic from the VPS to my homeserver and vice versa. Are there any other ways to solve this issue?

VPS Info:

OS: Debian 12

Architecture: ARM64 / aarch64

RAM: 4 GB

Traffic: 20 TB

    I’ve added some different ports for the future, but this is my ufw status:

      I can’t recall if ufw opens both TCP and UDP or just TCP by default.

      Try explicitly allowing 51820/udp with ufw allow 51820/udp

        I’ve added the firewall rule and it still says no port[s] to connect to whenever I run echo "Testing" | nc -u SERVER_IP -p 51820. I feel like you’re trying to stay on a sinking ship, so I would suggest to try another method to see if we even can get the whole “bypass CGNAT with a VPS” thing to work at all.

        Update: I’ve tried setting up SSH tunneling instead and it STILL doesn’t work. I contacted Hetzner support about this issue and I’m hoping that they can resolve the firewall issues that I’m having.
