[NCLUG] firewall nic config

On a firewall with one ethernet card for connecting to the LAN and one connecting to the Net is there a way to set the netmask or something else to split a class C so that most of the addresses are on the inside and only a small number are on the outside? If not, is there any reason I couldn't add 2 more NICs and at least set the netmasks for the 4 NICs each have a quarter of the class C and connect three to an inside hub? I've never configured a firewall (ipchains) for more than 2 interfaces. Is it doable?

Peace, William
