Need help setting up Redhat as a dial on demand router

["Bill Sandiford" <sysop interlinks net>]

Help :

I need a hand (or point in the right direction) for setting up redhat as a
dial on demand router.  I already have the ppp connection configured and
working properly.  What I need to do is figure out how to make it
automatically dial when it receives traffic headed for the internet on the
network interface, and then drop the call after a small idle timeout.

I have read the PPP Howto which deals with how to automate the dial process
using the pppon script but that still requires a human to type pppon...what
I need is for the interface to automatically come up when there is traffic
and automatically go down when the traffic is done.

Also, how do I add a network card to the machine...I have added a new card
but it did not detect it.  It is a Realtek Based ISA Card.

Thanks in advance
Bill
