Question

windows 10 pro

I setup the VPN connection, using L2TP/IPsec with pre-shared key and setup the user name and password. I go into the adapter settings, security and select Require encryption and PAP.

once I save and go back to the VPN connection, it is changed to general authentication and all user information is gone. This is on a computer where the VPN connection used work. after windows updates last week the vpn no longer works.

Hi,

I have also tried this with your steps and the settings are saved.

• Have you tried creating a new VPN connection?
•  you also could try to change your setting via the Set-VpnConnection PowerShell command to see if it could be remained:

/en-us/powershell/module/vpnclient/set-vpnconnection?view=win10-ps

Hi, if I may add a "me too" to this question?

Running Microsoft Windows [Version 10.0.17134.590] with all current updates.
The key "AssumeUDPEncapsulationContextOnSendRule" DWORD and Value(2) is in HKLM\sys\CCSet\Services\PolicyAgent.

I have created a VPN connection - L2TP and no matter what I do I cannot get the PreSharedKey password to save. Everytime I set it and attempt to connect I get an error.

"The L2TP connection attempt failed because the security layer encountered a processing error during the initial negotiations with the remote computer"

I have tried using PS command:(e.g. only)
Add-VpnConnection -Name "VPN" -ServerAddress 192.168.1.225 -TunnelType L2tp -EncryptionLevel Optional -AuthenticationMethod MSCHAPv2 -SplitTunneling -L2tpPsk "C0mpl#x1#" -Force -RememberCredential -PassThru

But the PSK password is still not saved.

I suspect a driver or something is messing up the Networking but I am getting to the end of my knowledge on this ... searching for help ends up in many forums like this all with no answers at this time ...

Can someone point me at ways to troubleshoot / resolve - the answer above does not work,
