We have an ASA 5580 with version 8.2 and looking to provide a solution for some outside vendors who need a L2L VPN with our site. Is it possible to have a L2L VPN tunnel where traffic across it is not permitted until someone authenticates with credentials? If it is I would appreciate any assistance.
It is my understanding that with L2L VPN that the authentication is done between the two peer gateway devices. And that once they have successfully authenticated and brought up the tunnel that any traffic from one site would pass to the other site without requiring any additional authentication. There is, of course, the option that within an application to require authentication from a user before processing of that application will will begin.
