Well, as for the pinging problem, do you have IP forwarding turned on? In the /etc/sysconfig/network file: FORWARD_IPV4=true Once the network service is restarted, they should see each other again. If you expect these other systems to have access to the WAN by way of this machine, however, you'll need to set up NAT, which is done using iptables (usually, by way of an iptables configuration front-end such as guarddog, firestarter, Bastille, or the Mandrake Control Center's applet, which uses the shorewall system). You can also set up your iptables rules manually, if you're so inclined, and use the "iptables" app itself to save them and to load them. Check the iptables man page, and such 'net resources as the Linux Documentation Project's HOWTOs and the home pages for the netfilter project (which includes iptables) and for shorewall. http://www.tldp.org/HOWTO/HOWTO-INDEX/networking.html http://www.netfilter.org http://www.shorewall.net -- Bill Mullen [EMAIL PROTECTED] MA, USA RLU #270075 MDK 8.1 & 9.0 The engineer is neither optimist nor pessimist.
