howto: firewall for ppp interface only and accept all eth-traffic

["A.J. Bonnema" <abonnema xs4all nl>]

Hi guys,

I read your advice on using firewall tools, so I started using 
firestarter. Now I have the following problem. My network has two 
internet connections I might use:

1. eth1 = internal traffic + traffic from the internet through a 
physical router/firewall

2. A connection through my telefone line which I will use if the ADSL 
connection is down.

So what I need is for all traffic from the eth1-card to be accepted and 
all traffic from the telefone line to be scrutenized by the fire wall.

Using firestarter, does anyone know how to do this?

Guus.
