I’ve set up a VPN\u00a0 Server on a Windows Server 2012r2 which I usually access from my iPhone or Macbook pro. Once the correct ports are forwarded it was pretty simple and always worked. I recently tried to connect from my Windows 7 machine and my Windows 10 machine both without success.<\/p>\n
The Windows 7 error was:<\/p>\n
809: The network connection between your computer and the VPN server could not be established because the remote server is not responding…<\/p><\/blockquote>\n
and the Windows 10 error was:<\/p>\n
File Metadata optimization is already in progress.<\/p><\/blockquote>\n
For this test\u00a0 my server was behind a NAT but the clients were not. Since neither the iOS or MacOS systems were behind a NAT, I felt that the network configuration of the server was not contributing to the error.\u00a0 Nevertheless, I searched for\u00a0 ‘errors’ ‘nat’ ‘vpn’ and I got a hit for at Client behind NAT devices<\/a>.<\/p>\n
I made the following registry change specified in the post for both the Windows 7 and Windows 10 client machines:<\/p>\n
HKLM\\SYSTEM\\CurrentControlSet\\Services\\PolicyAgent
\nRegValue:\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 AssumeUDPEncapsulationContextOnSendRule

\nData Value:\u00a0\u00a0\u00a0 2<\/p>\nThen rebooted each system and they both now connect to the VPN server.<\/p>\n","protected":false},"excerpt":{"rendered":"
