We are running PostalMate software 7.3.1 which utilizes Firebird 2.1.1. PostalMate creates a standalone Firebird database for every PC that will run PostalMate. After the software has been installed on each machine, one PC has to be the master. Then the remaining PC will be an auxiliary to the master. We have 2 machines one is the master and the other should be the auxiliary. Both pc's reside behind a SonicWall hardware device which uses McAfee Antivirus software.

However when trying to change the from a standalone status to an auxiliary we receive the error message.

I have allowed port 3050 for Firebird to be open but the error still occurs. I have even set the SonicWall service and the associated McAfee services to a manual setting, rebooted both PC's and I still have the error.

Both PC's have static IP addresses. They have the same DNS server as well as the same search order of DNS servers. I can ping either machine by either IP address or hostname.

There maybe something I am overlooking in the SonicWall interface, or something in the networking environment. I have added the ip address and host name in the host file in the event that was an issue.

Any help would be greatly appreciated.
