Feature
1

Hello,

I hope someone can help me.
I would like to setup a VPN Connection between Windows 7 and Nethserver.

I have installed both certificates CA and user.p12 (computeraccount) and setup the standard installation for vpn.
L2TP/IPsec ist activated and a user with password is created.

The vpn typ in Windows7 is IKEv2 with Computercertificate.
The connection is in lan green (no internetaccess required).
Has somebody a link for a Tutorial?

thank you

Nicky

It seems that nobody likes L2TP (I use openvpn).
I found some instructions on cisco website (search for windows l2tp).
