[NEBULA] Connection VPN L2TP Over Ipsec from windows

dbarchitectes

Hello,
I have a NSG50 and a DMZ configured on my router.
I configured VPN L2TP Over Ipsec with a shared key and a vpn user authentification.
All it's ok since my smartphone but not from a windows 7 or 10
On my different windows 7 or 10, i configured the register key "AssumeUDPEncapsulationContextOnSendRule"
 I configured VPN connection Properties as seen on the forum, for protocols (chap etc...) 
Nothing. 
Could you tell me if I missed out on a configuration for windows 10 computers ?

Hi @dbarchitectes

L2TP IPSec on Windows 10 problems are known.

Quick solution is to execute, and reboot the pc

REG ADD HKLM\SYSTEM\CurrentControlSet\Services\PolicyAgent /v AssumeUDPEncapsulationContextOnSendRule /t REG_DWORD /d 0x2 /f

But I suggest to read the following links:

https://superuser.com/questions/1298513/l2tp-ipsec-vpn-fails-to-connect-on-windows-10-works-fine-on-ios
https://github.com/hwdsl2/setup-ipsec-vpn/blob/master/docs/clients.md#windows

I hope it helps you.

Best regards

@dbarchitectes
Have you try to reboot?
I got experienced last time, reboot the PC to apply the change.

And thanks for @Alfonso sharing the command.
@Mickaël Is your setting is same as the following screenshot? Please don't hesitate to let me know if the issue still persist, I can help to cross check.

Hello,

Thank you @Alfonso . It's ok.

When I did it in manual, it did not work but it is ok with the command line, in short, it works and it is the main one.
Do not forget also advanced properties also as explained in the link, but for me it was already done.

It works for me too !

Thanks
