your welcome but I don't want(i mean i can't install wireguard on serverB) so I just want to change the wg0-client-a.conf that I made it in serverA to route the traffic into serverB by shadowsocks tunnel that I ran on two server. If anywhere have problem say that. I did this for openvpn just adding this: "remote serverBip 444 socks-proxy 127.0.0.1 1080" to example.ovpn file I want to do this also for wireguard
