Branch office 6x disconnecting from primary controller. I can rejoin but after a while it will disconnect. This branch office is (as of 11/20) running a fiber connection into the building. I have the remote 6x set in LAN host only mode with the default local subnet gateway and with the external public IP. I have a SonicWall TZ 400 configured with an access rule to connect to the SIP proxy. Connecting/registering to the SIP proxy is not a problem. The issue is calling other remote 6x devices extension to extension. I'm sure it has something to do with my SonicWall since it was working fine prior.

You say you're sure the SonicWall is at fault. By previously, what do you mean? What was the network topology when it worked? It might be helpful to draw this out.
Again, if attachments worked in this forum it would make troubleshooting much easier.
