I have a customer whose sonicwall we have just replaced with a Balance 30 for the cellular backup. Because the customer has a tin box for a building, they have a cell phone repeater called a Metro Cell from AT&T. After we put the firewall in, the Metrocell would not connect to AT&T servers (it does so via the network and then the device broadcasts a cell signal). I have configured in the firewall for the device to allow any for incoming and outgoing as well as entered to allow communications for the specific servers to allow anything coming in, and yet the thing will not come up.
The customer is Benzie Bus and I have remote support turned on. The internal IP of the Metro Cell is 192.168.50.132. Any help would be appreciated.
