Hi,

sorry for never replying to your mail.  It was on my TODO list, and
David regularily reminded me that it was there, but well...

I have now solved the underlying issue in a slightly different way - only
add the gateway spec if needed (aka: tap interface and not directly connect=
ed
network).  Patch has been sent to the just just now.

The BSD code didn't work the way you had it, because their route tool
is a bit weird - "-iface dev" must not be combined with a gateway spec=20
- if you do that, you end up with completely weird entries in the routing
table that do not work at all.  So the code now does either-or, depending
on interface type.

This is more "lamentable" than intentional - it's because I could not find
a way to actually specify the TUN interface for the route, or because the
documented way did not work.
