Corrections for a number of VPN issues that have plagued some versions of Windows since this month’s Patch Tuesday are coming.
Microsoft has finally confirmed that last month’s Patch Tuesday introduced connectivity issues on servers with Routing and Remote Access Service (RRAS) enabled, noting that client endpoints may also have difficulty connecting to these servers, experiencing connection drops.
The fixes will likely arrive as part of the July Patch Tuesday, which means affected users will need to be a little more patient.
While Microsoft addressed these issues in last week’s optional Windows cumulative update previews, these were only test patches, available to users of Windows 11, Windows Server 2022, and Windows 10, version 1809.
Those with newer versions of Windows 10, Windows 8.1 users, as well as those still using Windows 7 SP1 will have to wait for the July Patch Tuesday to fix the issue. This also includes some Windows Server users.
“We are currently investigating and will provide an update in an upcoming release,” Microsoft said.
As usual, those who are unable to patch their systems right away can use Microsoft’s recommended solution, which is to temporarily disable the NAT feature on RRAS servers.
“If the latest Windows updates cannot be installed on an affected server, the problem can be avoided by temporarily disabling the NAT feature on the RRAS server,” Microsoft said. “For steps and guidance on this, please note the ability to uncheck the ‘Enable NAT on this interface’ option described in step 7 of the Enable and Configure NAT article.”
Microsoft describes RRAS as a software router and an open platform for routing and networking, enabling companies to provide routing services in LAN and WAN environments, or over the Internet, with the help of secure VPN connections.
