Re: Setting up IPv6 wg tunnel

[Greg Troxel <gdt%lexort.com@localhost>]

Your logs are miswrapped (well, they are wrapped).

Your VPN server is repsonding that it has no route to the destination
address.  That seems odd, but it may be that private source addreses
aren't allowed to use global routes because of some scoping rules.

I do not know that fd=>global NAT works at all.   I do not know that it
doesn't.  Only that I have never tried.

Check that you have net.inet6.ip6.forwarding enabled.

I always recommend when debugging

  netstat -s > BEFORE
  [do experiment]
  netstat -s > AFTER
  diff -u BEFORE AFTER

In your case, I'd try to have not much happening, and do ping6 from the
client as the experiment, experimenting with ping options to get maybe
10 pps for 10 s.  you want a big enough signal that you  can see it in
the counters.

The point of capturing all stats, rather than looking at specific ones,
is that you find changes in counters you weren't trying to look at and
might not even know exist.  I'm not saying this will 100% solve your
problem, but it is easy to do.
