    VPN - PPTP vs L2TP

    Can I get some opinion on PPTP vs L2TP VPN on Server 2003 for a small
    business?

    I originally thought L2TP with a pre-shared key would be best, but then I
    found this:

    "PPTP using MS-CHAPv2 or EAP-TLS authentication is more secure than L2TP
    with pre-shared key authentication".

    Any thoughts appreciated.
    Russell.

    Re: VPN - PPTP vs L2TP

    I beleive L2TP is more secure. Quoted from Microsoft:

    PPTP connections require only user-level authentication through a
    PPP-based authentication protocol. L2TP/IPSec connections require the same
    user-level authentication and, in addition, computer-level authentication
    using computer certificates.


    Also check this search result.

    Which one is better, L2TP or PPTPA: PPTP is comparatively less secure than
    L2TP because L2TP does per packet authentication and integrity check using
    IPSec. But PPTP is easy to deploy. ...

    Hi Russella,

    L2TP has several advantages over PPTP, as you can see here:

    I think what you read is wrong.

    Both use MS-CHAPv2 or EAP-TLS authentication.

    L2TP uses IPSec based encryption on top of that.
