I live in a country where wireguard, openvpn and other vpn protocols have been blocked. Tailscale and Cloudflare Tunnels don’t wok either. I do have a public ip and my router supports DMZ and port forwarding. For security concerns I’m not willing to forward ports. Is there any other method to use my VPS to forward traffic to my home server?
Quick glance at the script shows it does randomize the port (but in the upper end of the space), but does not do preshared keys.
The PSK can hide the protocol better by not looking like a key handshake. Although I’m not sure ISPs have quite reached that level yet.
If you’re in China, there’s been some recent research showing that they block things that looks encrypted based on the entropy of the bits in a packet. I couldn’t find the bypass software anymore but that might help you as well.
If you’re not in China something like the XRay/v2ray proxy or shadowsocks might help as well.
Although honestly, port forwarding with a firewall only allowing your VPS IP should honestly be fairly sufficient security-wise. You could also try inverting the WireGuard connection and have the VPS connect to your home through port forwarding, traffic analysis is usually on egress not ingress.
