PtP should be correct, but it is possible that as wireguard is a new
thing,
it has broken multicast handling. Generally, PtP tunnels should have no
problems to use multicast - just send everything to the other side.
But as the tcpdump on one side shows periodic hellos from both sides,
then it is unlikely to be an issue.
The dumps I've pasted were on both gws and I don't really see it
going through, I only saw the broadcast but never any kind of answer to
it or coming out on the other side, so there still might be an issue.
Also i saw that your config files do not have 'log' option, so you have
no logging. You should enable logging and see if there are no error
messages.
I didn't paste the log options from the conf, they're at the top, but
you're right, I should have enabled debugging as well to get a better
view.
Although unrelated, i would suggest to remove these OSPF options;
tick 2;
rfc1583compat yes;
Care to elaborate why? I do trust that you will know better.
