At times I would like to strangle myself. WHY did I ever create private
addresses for IPv4 and thus create a market for NAT boxes????? Well if
I have not been involved, it would have still happened. The use cases
were out there and ROAD was dead. Enough handwringing. We have Nasty
NATs and mobile devices pop in and out of them. So we have to relay.
But only the WiFi connection would get behind bad NATs. My testing over
Verizon Wireless has worked well without relaying. So one MIGHT think
that with LOCATORs we could say that this locator need not relay, but
this better. Of course the phones have this tendency to roam and
perhaps not all cellular providers are set up not to need relaying....
Andrei's lecture notes do not cover the relay server part, only rvs and
I3 stuff. I am looking for some slides to cover relay.
thanks
