@psherman Hey - one last thing before I let this topic auto-close...
I just wanted to record here that your suggestion to replace the public DNS alias of my home lan (on the Peer configuration tab) with the internal IP address of my Wireguard Server did work. It allowed me to test the wireguard connection to my home, from my home (without having to enable hairpin NAT). That's a useful tip for anyone else trying to troubleshoot in a similar environment.
