I have several Dell SonicWALL's in service but with one of them, a TZ205 wireless-N, I can't remotely manage the Sonicwall. I can connect to all computers at this remote location from a VPN tunnel, Site to Site. If I connect to a PC behind that SonicWall I can then connect and manage the SonicWall. This is an extra step that I don't want to have to deal with.
I've compared settings to my other SonicWalls's but none are the exact same model. As far as I can tell everything is the same.
What am I missing?
