Internet | | | eth0 (public IP) Firewall/dhcp server | eth1 (192.168.1.1) | | Hub/Switch<--- Internal network (20-30 PC's) We are setting up a firewall/dhcp server. The dhcp server will run on eth1 and I think I know how to set it up (it seems to be easy with Yast2). SuSEfirewall will see eth0 as the external interface and eth1 as the internal. How do we pass the internet traffic from eth1 to eth0? Is it by setting the public IP to be the gateway for eth1? Is it possible to prevent certain PC's from having access to the internet? cheers, alberto ------------------------------------------------------------------- Alberto Santana, Ph.D. Center for Chemical Sensor Development for Explosives Department of Chemistry University of Puerto Rico - Mayaguez P.O.
