Determining ports for Cisco VPN client

I'm trying to create a policy to allow specific workstations to connect through a Cisco VPN client to one of our partner businesses.  The client is:

Cisco Systems VPN Client Version

It is using "Enable Transparent Tunneling" by "IPSec over UDP ( NAT / PAT )"


My problem is determing exactly which UDP ports this uses.  Based on info from our partner site, I've attempted the following UDP ports to no avail:







However, if I set the policy to allow ALL UDP ports (1-65535) then the connection is successful. 


Is there an easy way of discovering which ports are actually being used?

    Sorry about not responding earlier, it appears that you are good to go.


    I just wanted to mention that the audit viewing would be good in this situation as well. You could see what port(s) the firewall was blocking.
