Tor is miserably slow.
Discussion
Dont get me wrong, tor is an incredibly important tool for freedom, but it does not serve as a realistic solution to remote access for self hosted networking equipment.
Maybe you should bring this up with Start9? I'm aware of Tors limitations, but it's worked fine the few times I've tried it. Guessing if anyone wants to stream video from their server it could be a problem, but accessing basic files and pictures seems to work fine.
