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?
Alright, I switched to ufw and… it’s still not working. sigh
Should we just try something completely different? WireGuard doesn’t seem to be working on my VPS. Someone in the comments mentioned tunneling via SSH, sounds interesting.
That would work, but I’ve noticed performance isn’t as good as a UDP VPN that uses the kernel’s tun module. OpenVPN is also an option, but it’s a LOT more involved to configure (I used to run it before Wireguard existed).
The oddest part is you can’t get a netcat message through. That implies firewall somewhere.
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.
