You don't even need to go that far. I've seen routers of this sort running on 386/40's with 8 MB of RAM. So if you have any old motherboards lying around (or your friends, workplace, etc.) do, put them to good use and build yourself a router box! Right now, however, I've got my router running on an AMD 5x86/133. It's very inexpensive, reasonably fast, and can be used to do "real" work as well as routing work. My machine has 32 MB RAM in it, but even 16 MB will do you nicely. You will need *two* Ethernet cards in your router machine. This is because, in reality, you are setting up two completely different networks. Your Internal network will be running on one of the ethernet cards, and the external network (i.e. your cable modem, and the path out to the Internet through it) will be running on the other. The "router" software that runs on your machine bridges the gap. Once you've set up the two Ethernet cards properly, got them working, etc., you will need to set up the router software. Take a look at the NAT (Network Address Translation) program (view the manual page for natd(8)). This will take some doing to set up, so be forewarned. - --- Donald Burr <dburr@POBoxes.com> - Ask me for my PGP key | PGP: Your WWW HomePage: http://DonaldBurr.base.org/ ICQ #1347455 | right to Address: P.O.
