Possible regression between 5.18.2 and 6.2.1

[Jason A. Donenfeld]

Hi Dan,

Hard to imagine that this is a WireGuard bug, but more likely
something having to do with SNAT or something.

What is the unallowed src IP when you get that error? Can you debug
further? Maybe bisect a bit? Otherwise, not much I can do.

The diff between those versions you listed is pretty minimal, so I
suspect your bug is elsewhere.
