What worked for me after talking to Direct TV and getting nothing...
was that I had to move my Genie Go 192.168.2.237 outsi via the the DMZ
I verified that this opened the ports 8088 8089 by using the open port check tool on the internet..
I set up the virtual router
port forwarding, but the ports to the outside world did not work
till I move the Genie Go out the DMZ
