Hey Roman,

I've just tried a few ways of replicating your setup, and I can't seem
to reproduce the bug, either with the new code or old. The results you
mention are surprising too, since WireGuard or not, TCP is supposed to
negotiate the lowest common MSS. I wonder if some strange iptables
rules are getting in the way and confusing things?
