It's not too hard to do, and SusE and yast make it easier. I'm running
a setup like you describe right now. Basically the steps are:

- Setup the SuSE firewall on your server, the box with the modem. You
need to identify the external network, probably ppp0, for protection
according to the firewall rules, and the internal network, probably eth0.

- Put your DNS resolution IPs (get them from your ISP) into
/etc/resolve.conf as "nameserver", or enter them into the network card
setup in yast. Only do this on the server.

- I've seen people insist on setting up DHCP and bind (DNS) from the
start and have lots of trouble. Unless you have good reason, I think
it's best to start with a simple system and then learn and add things as
you go.

- In the client machines, use the network card setup to add the server's
IP as the gateway and nameserver.

That should get you going. You should now be able to ping and access
any PC on your net by IP. You can add machine names into /etc/hosts and
resolve them by name. You should also be able to access the internet
through your server. Your address requests will be forwarded by the
server to your ISPs resolver, so that work is done for you.

This is off the top of my head. If I've been obscure or forgotten
something feel free to write on or offline and I'll be happy to help.

BTW, your reference page had good advice, but it's easy to see that the
language is both correct and difficult. You'll understand it quickly as
it falls into place.

Good luck,

Jim
