How does Dish Anywhere get through my firewall?

[Alan Rovner]

Hi guys I have a two part question. When I'm at the airport or Starbucks and I access Dish Anywhere on my phone how does it connect to my Hopper at home? There is no port forwarding or any changes to my router. The same question applies to my newly installed Nest thermostat. How can it read the settings of the thermostat from the outside. Both the Hopper and Nest can obviously initiate an outgoing connection but I wonder how the incoming part works. Thank you, HNY, Alan Rovner

Could Dish Anywhere initiate something through Dish's end that sends a command via satellite telling the Hopper to making an outgoing connection ? If it did that, your firewall will then allow back-and-forth communication. Obviously that's not applicable with Nest....

It's a feature of your router called UPnP that opens portforwding on the required port to connect to the device.
