Site-to-site VPN goes down in Windows 8.1 or Windows Server 2012 R2

This article describes an issue in which site-to-site VPN goes down in Windows 8.1 or Windows Server 2012 R2. A hotfix is available to fix this issue. Before you install this hotfix, see the Prerequisites section.

Symptoms

Issue 1


The issue occurs when you try to start an Internet Key Exchange v2 (IKEv2) exchange during the initial VPN connection establishment on a certain third-party VPN device, such as a Cisco ASA. During the initial exchange, if these third-party devices expect a traffic selector other than the Microsoft default selector, they reject the initial connection request, and the tunnel establishment fails.

Note The traffic selector is the setting for endpoint networks that can send traffic over the IPsec tunnel.

Issue 2

This issue occurs during the IKEv2 rekey of an existing site-to-site VPN connection. During the rekey, the site-to-site connection may be disconnected under certain circumstances.

Cause

Cause of issue 1

This issue occurs because of the traffic selector ID mismatch in the IKEv2 connection.

Cause of issue 2

This issue occurs because the responder server uses an invalid traffic selector ID.

Resolution

To fix these issues, we've released a hotfix for Windows 8.1 or Windows Server 2012 R2.

Notes
  • This hotfix enables administrators to set a nondefault traffic selector on Windows RRAS Gateway that's running Windows Server 2012 R2, and this hotfix enables the interoperability for the third-party VPN devices.
  • After you install this hotfix, the responder server will use the correct traffic selector ID during the rekey.
