I did setup wireguard to my aws instance and my pc there is handshake according to wg command but can't ping my server(peer) neither my server can ping me and no connection to internet. I am not familiar with these kind of topics(familiar with networking but not setuping a vpn dns etc) so i don't know what config i should post here, but i am ready to post what you need to help me.
