The Layer 2 Tunneling Protocol (L2TP) launched in 1999 is an update on the Point to Point Tunneling Protocol (PPTP). It is a combination of the two protocols, the PPTP of Microsoft and the Layer 2 Forward (L2F) of Cisco. The L2TP protocol is a session layer protocol.
Whenever you visit a website, you leave a trail of activity in the form of your device IP address. Sometimes you do not want to expose yourself to the outside world and wants to hide IP address. You may not have control over ISP since IP address allocation is dynamic, but you can hide IP address with the help of VPN, proxy or TOR.
IPSec vs SSL VPN – Do you know the difference? An IPSec based VPN provides security to your network at the IP layer, otherwise known as the layer-3 in OSI model. An SSL VPN, on the other hand, creates a secure connection between your web browser and a remote VPN server.
The Newer versions of an iPhone and iPad have built-in VPN support. This makes it easy for you to setup a VPN connection on your iPhone. Moreover, you can also create a connection with the OpenVPN networks as well as other VPN networks by installing 3rd party applications such as ExpressVPN, NordVPN, TunnelBear, etc.
Some benefits of VPN include hiding your device IP address, securing the network while accessing public Wifi hotspots, cost saving compared to traditional leased dial-up connections, online anonymity, ads blocker, etc.
