This post will explain in detail How to Setting L2TP/IPsec VPN Client on Windows.
L2TP/IPsec VPN has a high level of security with IPsec encryption. With the high level of security in L2TP/IPsec, it does not mean that the configuration is difficult and complicated. Setting L2TP/IPsec client on Windows is quite easy, almost similar to PPTP VPN Client on Windows.
Unlike setting up an SSTP VPN client on Windows which is quite complicated because you have to generate an SSL Certificate first, for L2TP/IPsec you don’t need to use a certificate, just use a Pre Shared Key (PSK).
Before we continue discussing the L2TP/IPsec VPN Client Setting Tutorial on Windows 10, make sure you have read the previous Mikrotik Tutorial about the L2TP/IPsec VPN Server Setting Tutorial on Mikrotik.
Here I will demonstrate the L2TP/IPsec client configuration on Windows 10. For other versions of Windows, please adjust.
