What you're trying to do is actually a pretty common setup, which is good, cus there are lots of examples. To save yourself some time, there is a program that ships with mandrake called 'draknet' and could be really helpfull for you. Its a nice utility that will walk you through setting up a masquerading setup and firewall, and allow you to share your internet connection with machines on the internet network. It will also set up DHCPD for you on the internal network (which i'm not sure why anyone would recommend against) so your internal network workstations won't need to be manually configured. On top of that, it will let you specify some firewall rules, and set up a decent one for you.
Its more or less a front end to iptables, and once you've got the rules set up, you can look at the iptables configuration you have and go from there. Good luck, shout if you have more questions :)

have 2 ethercards :
eth0 is IP 10.0.0.10 and WAN-connected to a ADSL-Modem;
eth1 is IP 192.168.10.8 is LAN
this machine should be the firewall AND masquerade.
Dont't know if it is a good idea to have a dhcp running on it or not.In
some docs it will be recommended, some other docs says NO - anyway - first at all a masquerade and firewall should be the first
things, which should be realized - so I think.
