I've found that Native Access 2 does not play well with my very effective Internet boundary protection. I run a Ubiquiti Dream Machine for boundary protection and whereas the old NA was perfectly happy NA2 just sits at waiting for connection. If I activate a VPN on the computer running NA2 then it works perfectly. Seems like NA2 is doing something that is considered naughty and by running it with a VPN the encrypted traffic is then let through. If I can find the time I might get a wireshark trace and see if I can see why the Ubiquiti doesn't like what NA2 is doing.
YMMV, just putting this out there for info.
