Double authentication (User & Machine) with VPN SSL

[Peyman <peyman.secu () gmail com>]

Dear all,

  I was wondering if with a VPN SSL solution, it is possible to
authenticate the user and the machine both, with their certificates.
  I know that this could be possible with IPSec Over L2TP (machine
authentication with L2TP, and user authentication with IPSec), and not
possible with pure IPSec (just a basic login/password with X-Auth
available in IKE for a user authentication).
  Just to precise my needs :
    - I'd like to authenticate my users with a certificate because
this is useful for a remote vpn connection, and also for others needs
(emails, access to some ressources, applications, etc.)
    - I'd like to authenticate the corporate laptops with a unique
certificate stored securely on it : this is useful to only allow a
full network access to the corporate network to trusted machines, and
also to revocate certificates of laptops that might be stolen/lost.

Thanks a lot for any help,
Peyman
