Well if you are using NAT then you can say that ppp+ should be NATed to your extern interface.. should be to complicated? :) pppd brings up a new interface and adds a route to it, so you dont have to worry about this.

This interface is only active then the admin has made a dial-up on the server and has activated a ppp-daemon. In the time the ppp0-Interface is up the connections should be able completely in both directions and through to clients. But this should only alowed for connections via ppp0. Connections via the normal isdn0 should be protected by the normal firewallroules (iptables). How have I to configure.
