Curious to know if the 'saved the day' was really 'fell into a different
rate-limit bucket' for UDP by address family :)

Hell yeah!

So, moral / TLDR of the story?

Don't discount taking the time to set up IPv6, even if it's just for
your important devices. Also, WireGuard > IPsec.

This is great to hear.  I know that many things will operate better in
IPv6 land vs IPv4 land as in IPv4 land there’s a lot of port-based
filtering that happens in networks which isn’t the same in IPv6-land.

Super glad to hear that IPv6 saved the day for you!
