Hello,
I have CHR on DigitalOcean. this is Site-A
and
Site-B is behind the NAT
Can you please help me with the configuration of how to configure Wireguard between Site-A and Site-B?
I have tried but unable to handshake tunnel

Sure setup up the CHR as the server peer for handshake, and set up the ground router behind nat at the client peer for handshake.
many examples in the forum
