Different VPN tunnel types in Windows – which one to use?


Hello Folks,

 

I am sure you must have experienced VPN reconnect – a new IKEv2 based VPN tunnel that is added in Windows 7 that allows automatic and seamless switchover of an active VPN connection when the underlying Internet interface (connection) changes thus maintaining application persistence.

Isn’t that COOL – like VPN user moving from Wifi to WWAN and back –  giving a true mobile connectivity to corpnet ! Yes it is…

 

This means, Windows7 in-built VPN client and Windows 2008 R2 in-built VPN server (aka RRAS) supports following VPN tunnels:

·        PPTP

·        L2TP/IPSec

·        SSTP

·        VPN Reconnect (or IKEv2)

 

I am sure you must be wondering what is the need for 4 different tunnel types and which one to use in a given scenario. This blog helps to clarify the same.

 

Let us look at the technical specs which tries to summarize the tunnel features based upon different deployment factors:
