Thanks for the hint. For what i would like to do i probably will go for radius. I know thats not the right list, but maybe you (or somebody else) can help me out: - installing radius server on the poptop server? Okay/Not okay? - accessing one radius server from different poptop servers - which means havin one authentication server for different vpn/physical servers? - ensure that only my vpn servers can access the radius server? Probably ip restrictions? Any source that i might have to read? Regards, Sascha Kiefer -----Original Message----- From: james.cameron@xxxxxx [mailto:james.cameron@xxxxxx] Sent: Dienstag, 6.

I've heard of various ways to implement it ... a RADIUS server, or pppd ip-up.d scripting, or pppd authentication plugins. You would have to assume that an originating IP address identified a workstation (which isn't always true). But yes, certainly *possible*.
