If you want to do it the easy way, run IPCOP on your firewall box.

IPCOP is a dedicated linux based firewall that you can configure via 
a web interface.  It supports dialup PPP, DSL, ISDN and cable modems.
DHCP is an _optional_ service on IPCOP too.

You can download IPCOP, or buy a CD through KLUG.
