You cannot establish an IPsec connection between a Linux operating system and a Windows Vista operating system when you initiate the connection from the Linux operating system

SYMPTOMS

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.

CAUSE

In IPsec negotiation for transform proposal of the combination where Authentication Header (AH) and Encapsulating Security Payload (ESP) are used for securing the same packet (AH+ESP), Windows Vista switches the order and replaces the packet with ESP+AH. This behavior breaks the negotiation. In this case, when you initiate the IPsec connection from a Linux-based computer, the Linux operating system proposes that the IPsec security format is AH+ESP. Therefore, the connection cannot be established.

WORKAROUND

To work around this issue, modify the policy to use ESP or to use AH.

You cannot establish an IPsec connection between a Linux operating system and a Windows Vista operating system when you initiate the connection from the Linux operating system

You cannot establish an IPsec connection between a Linux operating system and a Windows Vista operating system when you initiate the connection from the Linux operating system

Article ID : 950826
Last Review : May 28, 2008
Revision : 1.0
On This Page

SYMPTOMS

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.

Back to the top

CAUSE

In IPsec negotiation for transform proposal of the combination where Authentication Header (AH) and Encapsulating Security Payload (ESP) are used for securing the same packet (AH+ESP), Windows Vista switches the order and replaces the packet with ESP+AH. This behavior breaks the negotiation. In this case, when you initiate the IPsec connection from a Linux-based computer, the Linux operating system proposes that the IPsec security format is AH+ESP. Therefore, the connection cannot be established.

Back to the top

WORKAROUND

To work around this issue, modify the policy to use ESP or to use AH.
