As a follow up, wireguard-tools v1.0.20200102 also has the issue.
I did think of updating nftables to the latest, but that then started
dragging in too many other updated dependencies I wasn't comfortable
with. So, as nftables currently isn't used on Slack, I renamed the
binary so that wg-quick wouldn't find it, which allowed the connection
to be made.
Now all I need do is work out why the handshakes between client and
server are working, but traffic doesn't flow.
Cheers.
