This L2TP / IPsec protocol is a PPTP protocol combination with the VPN protocol developed by Cisco. With this combination, it is certain that the data encryption process that runs on the L2TP VPN protocol is higher than using the PPTP VPN protocol. For speed, this protocol also has a fairly high speed. While in terms of use, this protocol is not so difficult to use. Because the use of this protocol is almost the same as the use of the PPTP protocol, there is only an IPsec shared key that we must input on our device if we want to connect using the L2TP VPN protocol.
