@jimp Thanks for that - I must have screenshot the wrong thing. I've actually played around some more, and it turns out that I had a problem with the protocol. I had not realized that I set it up with TCP rather than UDP.
For those who might experience this, please note carefully, that for the Firewall | Rules | WANS, make sure the protocol is UDP:

This is different to Firewall | Rules | Wireguard, in which the protocol is Any:
