I have configured WireGuard server on the VPS, yes. But I am not connecting to it using my router. I am just using a wg config file on my home server to connect to it. And do I configure nftables or iptables on the VPS? Because the traffic from my home server is already set to forward to the VPS using wireguard. The proxy is set up on the VPS, not home server. I cannot change any settings on my router because I am behind CGNAT.
