Has anyone out there seen or heard of a hardware VPN client or firewall that supports IPSec on a PCI card. What I'm looking for is a Card that can go into a PC that establishes a VPN connection to my PIX when the PC is powered up. And its configuration should be independent of the PC itself, and protected from the curiosity of the user. I'm trying to eliminate the use of an external device which still maintaining an operating system independent VPN client.
