Enabling CISCO VPN Client Software through Customer Firewall

[pmvw]

I need to know what ports the CISCO VPN Client Software (5.0) in order to open up ports in a client's firewall.

The requirements may vary somewhat depending on what transport options you select in the client. But the basic setup would need to open up UDP 500 for ISAKMP and open protocol (not port) 50 for ESP/IPSec.
