I have a Cisco PIX 520 that I bought to learn the configuration of Cisco PIX firewall at home. It is running Cisco PIX Firewall v6.3(5) software with PDM 3.04. I also has six physical interfaces. I have configured the outside interface and the inside interface and my systems behind the firewall are able to go to the Internet and browse. Since I have four other interfaces on a quad firewall NIC, I would like to configure each of these interfaces for machines to go to the internet also. I have a couple of ideas from reading Cisco PIX books, but I also need the advice of experienced Cisco PIX firewall administrators that frequent this site, because I know you guys are damn good. Any suggestions will be greatly appreciated.
