Is it able to connect but not pass traffic or can it not connect at all? 
If memory serves correctly, the Cisco VPN Client uses adaptive measures 
when attempting to connect with a gateway. If it can't reach the peer 
using UDP/500, it will try the other methods automatically. You should 
be able to determine the actual connection method by enabling the Cisco 
client log output.
