Instructions for using the Cisco Client with Windows XP service pack 2

If you have upgraded your machine to Windows XP Service Pack 2, you may run into an issue with needed ports being blocked by the Microsoft firewall. This will cause the VPN client to no longer work. To fix this, a rule will need to be added to the Microsoft firewall to allow UDP port 62515.

This can be added either through the firewall GUI by adding an Exception rule, or you can add it by entering the following command from a DOS prompt: 
		netsh fi add port UDP 62515 "Cisco VPN Service" enable all
(These instructions and more detailed information on the Cisco client can be accessed at www.net.tamu.edu/network/vpn.html)
