I have perused the networking forum looking for information on authenticating users traversing a PIX-PIX vpn tunnel. I have seen several threads discussing remote IPSec client authentication using RADIUS/ACS/RSA servers, but have not found much, if any, information on site-to-site vpn's.
Can users traversing a site-to-site (PIX-PIX) vpn tunnel be authenticated against either a local (PIX)database or an internal RADIUS server?
Further to that, are the (site-to-site or remote) users challenged for each service (Mail, FTP, Telnet, HTTP, etc) that they try to access? Or can they be authenticated once and then permitted access to all services? Can other services be challenged as well?
Any info or URL's would be greatly appreciated.
Thank You,
Dan
