Hello, I've searched around and haven't been able to find a definitive answer to whether or not the Cisco VPN client supports AH. I seem to remember reading somewhere a while back that it only supports ESP tunnel mode. If anybody knows for sure, I'd appreciate if you could let me know.
When defining a Quick Mode Secure Connection for IPSec, PIX Firewall and Cisco IOS software can use both AH and ESP in a single Secure Connection, but the Cisco Secure VPN Client can use only one of the two per Secure Connection. I believe we can do AH and transport with the 1.1 client.
