No Love. Thanks for the suggestion, but it didn't do anything. I suspect that a previous post about the version of software is correct. The reason being: Our company has VPN servers in North America, Europe, and Asia. When Apple "Broke" the VPN function the last time, we were still able to connect to Europe (various users of Apple routers in the company). Then, when Apple fixed the problem with a firmware upgrade, we were able to connect to all three servers no problemo.
Now, with the 7.3.1 firmware upgrade, the problem returned exactly as it had before. To wit, we can still connect to Europe, but not the other servers.
