(I know wireguard, tailscale and so on are the preferred options. But for some reaon I can’t use any vpn atm)

I’m looking for some tunneling solution which:

-is NOT Cloudflare Tunnels

-doesn’t need a VPN (so wireguard or openvpn are ruled out)

-is not SSH tunnel

I need something like FRP preferably with a luci app and automatic ssl certificate for my subdomain.

Any recommendations?
