Internet Protocol Security, also known as IPSec VPN is a suite of protocols used to provide encryption for tunneling protocols like L2TP and IKEv2. Find out what it is and how it compares against SSL VPNs here.
Configure L2TP/IPSec Attributes for UMN L2TP Native VPN. Now we can define the attributes specific to the University's central VPN service. Navigate to Network and Sharing Center. > Control Panel > Network and Internet > Network and Sharing Center; Click Connect to a network. Configuring a Basic VPN for L2TP/IPsec in the WebUI. The combination of Layer-2 Tunneling Protocol and Internet Protocol Security (L2TP/IPsec) is a highly-secure technology that enables VPN connections across public networks such as the Internet. Our experience trying to use L2TP/IPSec on the Cisco RV340 has been a nightmare of frustration! It appear to mangle the PSK and thus never manages to establish the encrypted tunnel fully. It is difficult to debug and certainly is not a pleasure to configure because no combination of settings gets it to work. After finishing installation, go to “Control Panel” > “Applications” > “VPN Server” >”VPN Server Settings”, enable L2TP/PPTP VPN Server and select “L2TP/IPsec” and enter the configuration settings:* VPN Client IP pool: Enter the start and end IP addresses to define the IP range for the VPN clients to connect to the VPN server.
This definition explains the meaning of IPsec, also known as IP Security, and how IPsec is used to encrypt or authenticate Internet Protocol packets.

The inner layer comprised of an L2TP header and a UDP header wrapped around the PPP frame. The outer layer adds IPSec ESP (Encapsulating Security Payload) header and trailer to the first layer.
