Well, I'll tell you what I did, provide some examples, and maybe this will give you a quicker start.

It sounds like you're preparing a firewall/dialout box that connects you to the internet whenever one of your machines on your internal nettwork needs IP services/a connection to the internet.

(and from your next message):

Ok, the examples I'm going to provide use the standard for a class c internal network on 192.168.1.*, with a mask of I'll leave it to you to change that to 10.20.30.*, with the appropriate mask.

Ok, let's start with DHCP. I'm going to assume you mean DHCPD (the DHCP daemon) that you want to control what addresses the machines on your internal network receive. Your dialout connection will provide you with an address for your ppp0 link when you connect, so that angle is already taken care of.
