Maybe this is a bug or something I'm doing wrong but the Dude will not discover Canopy subscribers unless their internal NAT feature is disabled. I can manually add the devices and they ping fine so I'm confused why they cannot discover them. I even tried a fresh install of the dude 3.6 on a brand new server running win2003server and still could not discover. I also tried the latest beta build and had the same results. If I try 10 times in a row they might get discovered once but then if delete them and re-discover with the exact same discover options they wont. I can't make any sense of it.
