Hi Mike,

Yeah, you have to dog-leg through a provider that you don’t trust. Because the providers you don’t trust are the only things that home automation device manufacturers are assured by the actual existing Internet will be reachable from arbitrarily located remote mobile handsets. 

Home automation controllers and similar servers on home networks will not generally be reachable from arbitrarily located remote mobile handsets without some kind of standard solution to the problem described in section 3.4, Passive Listeners of RFC 6092, which is widely deployed now in most residential IPv6 gateways. Note also that REC-49 of that document is also widely ignored in most implementations, certainly enough implementations that it cannot serve as a dependable mechanism. It’s also important that REC-48 has mostly gone without further attention since, and that certainly adds additional complications.

Look on the bright side! Consider the possibilities that open before you when there is a 3rd-party provider that everyone can trust!

I’d like to calibrate my perhaps mistaken apprehension that nobody would seriously consider doing this. Everyone I know in this field plans to do this by providing a single public rendezvous point with high availability servers that communicate in turn to home automation controllers acting as private clients.
