I use a winXP Laptop and i installed the Cisco VPN Client 4.0.4 Rel K9, i don't know what is the problem with the laptop because it can't establish the connection. This is the message error:
"Secure VPN Connection terminated locally by the Client Reason: 403 Unable to contact the security gateway"
I installed the same software in another laptop with the same winXP and i don't have this problem.
I really appreciated your help.
