Hello,
Thanks for your answer.
When you explain that with L2TP Windows do 2 authentication, one for the
computer and one for the user, You want to say that the athentication of the
computer is the IPSec authentication and the user authentication is made by
the L2TP or that after the IPSec tunnel is mounted, L2TP try the 2
authentication modes ?
If in the L2TP try to authenticate first the computer, before the user, how
can I do to disable this first authentication mode ? The contivity VPN
gateway doesn't give any way to configure 2 authentications mode for the L2TP
account, only an user account.
