Hi,
Thanks for this article, i’d juste like to know what you mean by “set the client as SecureNet” ?
And instead of disabling the Firewall Client is it possible to set the vpnclient application key to “0″ on the firewall client settings?
Thanks for all
Geof

Hi Tom,
Thanks for your article.
But for some reason it didn’t help me. I am not able to connect to a VPN server using Cisco VPN client that is sitting behind an ISA 2007 box.
As per the article I have made my client a secure NAT.I am also able to browse the internet with the same settings. That means I am able to go out of the firewall BOX using a secure NAT client. I am also able to ping to all public IP addresses. For example yahoo.com, google.com
Please help me in configuring the VPN client.
Regards and Thanks
Vikrant
