Hello there,
I am working to configure a dynamic tunnel to our cisco asa 5505, yet there is a firewall infront of our cisco asa and we need to open ports for the VPN Client to be able to reach the cisco device.
May someone please advice as to what ports the Cisco VPN client uses?
as we must open this ports, any help would be appreciated.

-->IP protocol 50 (ESP), 51 (AH)
-->NAT-T port 4500

AH is not supported anymore on 7.x and above (so no ASA has ever supported it).
TCP/UDP port 10000 is common also for alternatives to NAT-T.
