Sharing the internet with MacOS X
Apparently it _is_ possible to share the internet over the same ethernet cable. So my iBook is currently functioning as both the gateway to the modem (providing internet to a pc), and as a computer itself, retaining internet abilities~

Come to think of it, of course it would work. There'd be no need to have two separate physical interfaces.

Why? Insight went and did a network upgrade of some sort. Which caused all netgear routers to fail when grabbing an IP from the network. So my netgear router is currently useless.

Now, the question is, can I share internet with my PC as well? Over one physical wire, mind. And turn that into a router?

The setup goes as follows:
Modem => normal hub port => normal hub ports to { iBook, PC }
I kept the PC disconnected while I grabbed an IP address on my iBook, then enabled sharing, and plugged the PC back in. And it all worked~ =^.^=

Sounds kinda similar to what I do. Mac OS should have the same capabilities as linux....

This is my personal abuse of the university network system, they never even know my laptop is here.....
Laptop -> server ethernet 1 (crossover cable) -> iptables ->server ethernet2 -> University jack

This is a setup that I made for a computer lab for elementary school students.
6 computers -> switch -> server with DHCP and iptables -> ethernet or modem to interweb
