WHAT IS VPN TUNNELING PROTOCOL?
When you connect to the internet with a VPN. its creates a connection between you and the the internet that surrounds your internet data like a tunnel,encrypting the data packets your devices send.
The level of encryption the tunnel has depends on the type of tunneling protocol used to encapsulate and encrypt the data going to and from your device and the internet.
While technically created by VPN,the tunnel on its own cant't be considered private unless it's accompanied with encryption strong enough to prevent government or ISPs from interception and reading your internet activity.
1]PPTP
["Point to point tunneling protocol"] PPTP is a networking standard for connecting to virtual private network,or VPNs.VPN are secure network that can be accessed over the internet,allowing users to access a network from a remote location.this is useful for people who need to connect to an office network from home or access their home computer from another location.
2] L2TP/IPsec [LAYER 2 TUNNELING PROTOCOL][INTERNET PROTOCOL SECURITY]
L2TP has such weak native security,many experts consider it a remote access technology rather than a vpn.on the other hand ,user tend to think of it as an VPN technology and are interested primarily in protecting their communications.one way of reconcilling these two views is to combine L2TP with an external security protocol.
IPsec provides encryption,authentication,and other security services at the network layer .IPsec can run in serveral modes and provides different security services,let us merely stipulate that IPsec can provides encryption and authentication for IP packets.
3]SSTP [SECURE SOCET TUNNELING PROTOCOL]
SSTP is a form vitual private network tunnel that provides a mechanism to transport PPP traffic through an SSl/TLS channel. SSTP is available for linux,BSD,and Windows.
4]OpenVPN
OpenVPNis strongest protection while online you should consider investing in a VPN services provider that relies on the Open VPN protocol.
Open VPN is currently considered the top form OF VPN tunneling protocol,Thats because its encryption is specially strong.its also adept at getting past firewalls.
This protocol works with all the major opreting system,linux,windows,and mac,on the mobile opreting system of Android and IOS.
