I've been beating my head against the wall trying to get Beacon working, and finally stumbled upon the realization that the Reflector isn't passing along the port that Geofency was connecting to (6192). I verified this by using my (current) external IP, and it works perfectly, but when I try to use the Reflector address, it simply drops the request into nowhere.
Is there some setting in Indigo that needs to be changed, or is this not possible with Reflector?
