My home wireguard server is in MT6000,In the external network,I used a non-inet series router to generate a wireguard client,How to add its public key to the peer of the home server?

Generate VPN profile in MT6000 WG server, and then import it into non-inet router WG VPN client, or on your mobile phone or laptop.

This no need to add the public key from client to the MT6000 WG server.
