pppd with demand dialing will do it on every packet. After watching the traffic for a while (iptraf) i decided to turn demand dialing off and to further deny connections to certain IP adresses at all. This windows and some apps feel very free to tell some servers (eg. microsoft.com) what is going on on your box. Meanwhile though we have a free system back here, because win is only once in a while running inside some emulator that allows even tighter control of the networking. As we are on debian-firewall, a closer look on firewalling and masquerading (you may start with the HowTo in the docs section) might be worthwhile. greetings, martin
