How to configure L2TP over IPsec VPN on Reyee EG?

Introduction of L2TP over IPsec VPN

l   L2TP over IPsec VPN usually is used for the Site to Site scenario and Client to Site scenario. For example, three branches of a company are distributed in three different places of the Internet, and everyone uses a gateway to establish tunnels with each other, and the data between the corporate intranets (several PCs) is securely interconnected through the L2TP over IPSec VPN tunnel established by these gateways, the staff who work at home can access company data through L2TP over IPSec VPN tunnel too.
