Hi Ján,

We never really figured out what a good interface for this would be for
normal SmartOS, so you've mostly found all the bits in Triton that
automate it there and make more sense there. I'll try and explain some
of the things you saw, but if you have ideas on what might make sense,
that'd be useful.

This was the design center for triton where we're not using direct
tunnels, but we effectively have an overlay per customer, so they're
much more dynamic.

The number in this case was designed to be a vxlan (or other
encapsulation protocol) identifier.

Right, it's really designed for point to point connections. There's an
open RFE about making sure you can use multicast groups, but beyond
that, folks will need to look at other search plugins with overlays to
plug into other directory services.

Hopefully that helps clarify a bit, sorry this was rather painful.
