Consider the following scenario. You use Windows Vista Local Security Policy on a Windows Vista-based computer. Or, you use the new Windows Firewall with Advanced Security on a Windows Vista-based computer. You try to initiate an Internet Protocol Security (IPsec) connection from a Linux-based computer to the Windows Vista-based computer. In this scenario, you cannot establish the connection.

Notes:

• If you initiate the IPsec connection from the Windows Vista side, the connection is established correctly.
• Windows XP and Windows Server 2003 work correctly with the Linux operating system in this environment.
