Pix 501 Authentication for outbound connection

I don't even know know if this is possible with the pix, but I believe it is if I'm reading the Cisco documentation correctly. What I'm looking at doing is while the PIX is constantly connected to the VPN I want the users to have to authenticate themselves when attempting to connect to any IP on the other side of the vpn. Then require them to reauth every 15-20minutes.

As I said I believe I can do this with the aaa-server in the pix, but i'm unsure how I would configure it.

Here is a example of the configuration I use in my 25 remote PIX's

Any idea on how I could achieve this then?

Here is a guide:

But again, this is fo remote access VPNs, not for site-to-site

Sorry, I meant achieve what I'm trying to do without using the Pix, since the aaa-server is for remote access VPN's. The have the VPN up, but require some sort of additional authentication required before the traffic is allowed.

The reasons I'm trying to figure this out is I have a couple remote locations that are having a 3rd parties VPN added into the network. The 3rd party is allowed to remotely control a couple of the computers. Computers that need access to both VPN's. So I'm just trying to boost our vpn's security to prevent that third party from even attempting to get into anything on our end.

The reason i need to leave the VPN up at all times, is because at any time I need to get back into the remote locations at any given point. Some times even after hours to do maintenance.

I ended up designing a captive portal system. Using a spare Linux server and converting it into a router.
