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?
A ssh tunnel probably is your best option
I think so as well and it is sad that that the OP has to be in a place where internet is so heavily censored.
