hi,,,

you can say tunnel is like virtual link...and it will hide your physical interface ip address...u can provide the authenticaion also at both end as well as u can establish the secure connection on it...

So, What's diffrence betwen VPN Network & tunnel network ?

[gpulos]

a vpn network is setup specifically to allow connectivity to resources on a private network while requiring the security & authentication.

a tunnel on a network could be setup to simply allow the finance department send secured data to the marketinng department.

a tunnel on a network can also allow for a certain protocol to be tunneled through the network that could not otherwise be sent on its own due to limitations in the network.
