Our Cisco ASA is configured to allow connections from the Cisco IPSec VPN client. Recently we've noticed our users with Verizon Internet are not able to connect to the gateway unless the Enable Transparent Tunneling option is disabled under transport settings. Once this checkbox is unchecked, the VPN connection is successful.
Some of our executives use the built-in Cisco client on the IPad to connect to the VPN. These users are not able to connect when on the Verizon network. I cannot find any way to check whether transparent tunneling is configured or not in the VPN Client.
So the question is "is there a way to make sure the built-in Cisco VPN c;lient is not using transparent tunneling?"
