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?
