There are fixes for various VPN issues that have plagued some Windows versions since Patch Tuesday this month.
Microsoft confirmed that the month-long Patch Tuesday introduced connectivity issues on servers with Dial-up and Remote Access Service (RRAS) enabled, noting that client devices may also struggle to connect to these servers, experiencing connection drops.
Most likely the fixes will be released as part of July’s Patch Tuesday. This means that users who are affected will have to wait for the fix.
Workaround available
These issues were addressed by Microsoft in the optional Windows cumulative update previews released last week, but these were only test patches available to Windows 11 and Windows Server 2022 users.
For those with Windows 10 and Windows 8.1 users, or those still using Windows 7 SP1, the problem will need to be fixed before July’s Patch Tuesday. This includes Windows Server users.
Microsoft stated that they are currently looking into the issue and will provide an update in a future release.
As is the norm, users who are unable to patch their systems immediately can use Microsoft’s recommended workaround, which is to temporarily disable the NAT function on RRAS servers.
Microsoft has stated that temporarily disabling the NAT function on the RRAS server may help if it is not possible to install Windows updates on the affected server. For more information and tips refer to step 7 of the Enable NAT and Configure NAT article.
Microsoft describes RRAS as a software-based router, and an open platform for routing and networking, enabling businesses with routing services in LAN and WAN environments or over the Internet, through the use of secure VPN connections.
