First of all, let me mention that some Cable Companies are heavily prosecuting people that share their cable connections. I do share mine but in my contract nowhere is written that I shouldn't, or that I should use only one machine. Only that I should use only one IP in the Cable network. Which I do.

Now, for the options:

I have used two options (am using, actually). I have four networks in two machines, and both need different types of sharing.

First I have a machine in a company network which I can connect to the telephone line for basic e-mail access. I share this connection with the ethernet network by using the command-line program ipfw (which I think Brickhouse uses internally). I have created a script called ip-up located in /etc/ppp that has the following (and runs when the ppp connection is activated):

/usr/sbin/natd -dynamic -interface ppp0
/sbin/ipfw -f flush
/sbin/ipfw add divert natd all from any to any via ppp0
/sbin/ipfw add pass all from any to any

This simply allows for address going to the ppp0 interface to be rerouted and their ip addresses translated. This also allows for the users in other machines in the network to use the route as well by adding "route" statements in their machines. This is a very rough and specific set-up.

Then in the house I have an airport network and a cable connection that I share with the Software Base Station (not from Apple) program available in versiontracker (and probably MacUpdate). This software enables the ipchains service as well (IP Forwarding) in the /etc/hostconfig file, gives out all the needed parameters for the server and clients and launches gNATd for the address re-routing and translation. It's a very simple set-up once set.

I will give Brickhouse a look and see how it works.

Of course, this all will be moot in three months, as Jaguar has this included in the OS..:)

The first method is exactly what brickhouse does only it does it in a startup file at system launch.

Basically brickhouse is a nice gui for ipfw and natd.

Sharing internally versus externally

No need to be an alarmist. If you pay for a cable connection you can share it inside your house as you wish. The main beef of the cable companies are people that are part of a city-wide wireless sharing network or free/network like warchalking or advertising on sites that have maps of free networks. So the cable companies aren't coming after people using a hub, a switch or a wireless LAN, they're coming after people that are giving away their service for free (or resale), which is spelled out in the TOS.

Hope this helps.
