Hehe ... dynamic oscillating system ( ugghh... yet another DOS ;) With my changes the interface fall back to the initial configured local-IP-adr or any other explicitly given IP-adr. This was due to the dynamic-system-games i had to play with my firewall when the interface was changing it's local IP-adr on each dialup. After the line was hung up, my firewall-let-through-a-dialup-trigger- packet-rule was useless. > >> Here is what i said: >> "In short, until the interface has not been assigned >> the dynamic IP-adr, the outgoing packets get a source-IP >> of 0.0.0.0" > > Now that you corrected my mistake we DO agree here :) Glad to hear that .... life could be soooo simple.
