#IPSEC VPN CLIENT FOR MAC PASSWORD#
Once we have configured it and clicked on «Save», we go to the «Users» section and create a username and password to access. Primary / Secondary L2TP DNS Server: we can put a DNS server for the clients.Secret: 1234clavel2tp We can put a passcode, it is recommended to put it, although some clients do not require it.Number of L2TP Users: 10, this can be configured to suit the user.Remote Address Range: 192.168.100.128/25 We give a local subnet to connecting clients.Server Address: 192.168.100.1 We must put a subnet that is not in use, and that serves only to use it as a customer gateway.The first thing we must do is configure the L2TP protocol, for this, we go to the “VPN / L2TP” section, and configure it as follows: By having two protocols to configure, L2TP and IPsec, we are going to clearly divide the configuration into two parts. Once we have a summary of how both VPN protocols work, we will proceed with the configuration. For this reason, we will always find this protocol written as “L2TP / IPsec” in operating systems, because it uses both protocols simultaneously. With all this in mind, the IETF organization made the decision to use the cryptographic protocols of IPsec in conjunction with L2TP, to provide the confidentiality, authentication and integrity features of the L2TP tunnel. Also, L2TP does not encrypt the traffic from source to destination. It only allows authentication between the end points of the tunnel, but not for each of the packets that travel through it, the same happens with the integrity of the packets, it is not checked.
The negative part is that it does not present a robust cryptography, therefore, it is not safe to use it. This type of VPN protocol is multiprotocol, and allows access to remote local area networks. L2TP (Layer 2 Tunneling Protocol) is one of the most widely used VPN protocols, it makes use of the PPP protocol for the connection of the different links, in addition, it includes PPP authentication mechanisms such as PAP and CHAP, in addition to supporting the use of RADIUS servers for client authentication.
