Q. I have Sun server for web services, Ultra 10 workstation, a Dell 410 workstation, and three pc's. I want to install my firewall and have leased 5 ip addresses. The question is, what the best network configuration for me. I was thinking I should be able to drop the static ip for the workstations and use dhcp to server the internal networking. I have a switch, which will handle another 18 internal connections and I want to take the time to configure the system correctly before it gets out of hand.
