Why do you have two eth cards internally?  The first thing you may want to
consider is "Do I need two eth cards".  You may be making things unnecessarily
complicated.
If you only have the ppp interface and one eth interface, then what you do is
just replace eth0 with ppp0 in those tutorials and eth1 with eth0.
If you need both internal interfaces, then your changes are still not that complicated:
you'll need to use the rules the tutorials tell you to apply to eth0 on ppp0,
and the rules the tutorials tell you to apply to eth1 on _both_ internal
interfaces.

Good luck.
