Um, could you help us out by being a little more specific? Maybe if you
briefly outline the setup with dummy company names and then explain the
scenarios that concern you?

>From the post I can't tell if you're securing just your company, the network
itself (like if you were providing carrier services), all the
companies...you get the idea.

        Subject:        [Q] Firewalls and LAN dialup access

                Does anybody have any experience or pointers on how to
provide 
        security/protection for an Extranet type of info sharing among 
        different companies, especially against possible internal individual

        LAN users who (unwillingly or not, including not knowing of IP 
        forwarding being enabled ?!?) use dialup connections to the
Internet, 
        or a common proxy/socks/direct LAN connection to the Internet, if 
        each LAN "sits" behind a NAT router? I am also interested in 
        pointers to policies spelled out for the member participating in the

        Extranet, including how-to on identifying such behavior ...
                TIA,
                Calin
