Nope. Run winsock stacks doing native IP over ethernet alongside the IPX/whatever stack, put the FreeBSD box on the ethernet with the serial link out; put all of the internal systems on a fake IP net, disable routing on the FreeBSD box, and run a socks proxy on it. Presto; instant firewall, easy net access. You can run all your mail on the FreeBSD box using pop or imap, and with appropriate clients you can still talk out. You can put the CERN proxy httpd on the FreeBSD system as well, and take advantage of an organisation-wide web cache. This is easy to set up, and a very popular use for FreeBSD systems around here. > Gary -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] My car has "demand start" - Terry Lambert [[
