Full Disclosure: I always struggle with networking. In spite of being at this for ~40 years and IPv4 being simple in concept... I dunno - I always struggle making anything more advanced than basic firewalling and physical layer stuff work. It's so weird considering the stuff that I don't struggle with.
BUT!
Today I managed to make a Wireguard tunnel work on a OPNSense router that is behind another OPNSense router that is behind CGNAT outbound to the WG end point on a VPS and can now curl to the web host inside all these layers! <whew - say that five times fast!>
Everyone comes at things from a different direction and occasionally even a blind squirrel finds a nut. I'm just so excited I had to post. Ha!
