Difference between vpn protocols and tunneling protocols
You can see the question easy but not on google i find it
i note that they always mention 5 protocols
PPP, L2tp open vpn and others
but then i observe that they mention the word tunnel
and i see there is ipsec, Gre, dmvpn, flex vpn. ikev2 and how do i get confused
and also i see that it says l2tp uses ipsec it is very confusing all this issue
i am a student
There are protocols to create a connection: PPP, L2TP, VPN
Then there are the others... IPSEC = IP Security, so it will include a family of encrypting protocols, including IKEv2.
GRE, DMVPN, and Flex VPN are methods of connecting, used between routers.
My question to you is if you need a way to remember the differences, or if you are trying to solve a particular problem.
thanks
I would suggest PPP, L2TP, VPN are consumer grade solutions
GRE, DMVPN, and Flex VPN are commercial grade solutions
