Cisco VPN Client with Sprint Aircard (PCS)
Error 51: Unable to communicate the VPN subsystem. Please make sure that you have at least one network interface that is currently active and has an IP address and start this application again.
What is happening is the Cisco VPN Client does not recognize the AirCard's connection as a valid network interface, even though it is working and recognized by the Mac OS.
The Cisco VPN client works correctly using the built-in Ethernet and the built-in Wireless (802.11x stuff).
Note: The Sprint Aircard is a wireless PCS data card, it is not an Airport or similar card that uses the 802.11x technology.
Any help would be appreciated.
