I live on 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?
Wireguard is not meant to bypass detection of any kind of Deep Packet Inspection technology. It’s also stated by the project website, under the Known Limitations sections.

There are many characteristics (except the handshake) which can make it stand out as a P2P or VPN(-ish) traffic, and then get blocked.
