I'm looking for configuration options and based on what I've found in the mailing list archives is that I can either divide the class C up into subnets or run natd and give private ip's to all machines on the "inside" network. I am looking at the following layout: Cisco 675 DSL Router ---> FreeBSD box ---> internal network fxp0 fxp1 I would rather not assign all internal machines private ip addresses. I would also rather not divide a class C up into subnets and waste a bunch of ip's. Are there any other options? If not, I will proceed with dividing the class C in half. I've searched through the archives and it is unclear as to what I need to do in order to pass traffic from one NIC to the other. Any help or insight would be appreciated.
