Wow. So I'd made the assumption that this is just what I needed to do
to access lan resources.

Turns out "0.0.0.0/0, ::/1, 8000::/1" will allow that just fine on
OSX. I still get a broken system if I specify ::/0 as the default
route doesn't appear to get created but with using ::/1 8000::/1 it
seems to work around that.

Problem solved! Thank you.

Though it's not at all intuitive or expected. Is there some issue
queue or something this can be added to for the OSX client
application?

Thanks
Adam
