I did not think IPv6 was set up correctly prima facia.
It was exactly why I thought the leak was on IPv6. I was a little surprised there was an IPv4 leak too.
IPv6, IMNSHO is not deployed by most ISPs with the advantages baked in.
I'm sure it will reach a tipping point and at that point setting it up will actually be universally advantageous.
I'm sure, if you would still like, @psherman is still willing to help tidy up the guest networks.
