Note that Rutgers uses lots of dedicated little boxes, not UNIX beasties, as IP routers. The original question, which included a description of an attempt to install a second Ethernet interface in a Sun backplane, sounded as if they planned to use the Sun as an IP router between two Ethernets. In this case, you'd want to leave ipforwarding turned on, at least in the kernel of the Sun to be used as a router.
