Yes, this line was already there... Now I've replaced the calls to "adsl-stop" and "adsl-start" with "ifdown ppp0" and "ifup ppp0", respectively. That does work! Of cource, this is just a quick-and-durty, temporary solution to let my gateway provide Internet access to other clients... The next step would be to discover why pppoe suddently stops working... Could the dynamic change of the IP address play a role in this story? I've noted that after the script above restarts the ppp0 interface, ddclient notifies an IP address change... j3d. >>> > > >>> > > >>> > > >>> > > Any idea? >>> > > j3d. >>> > >>> > Here are a few thoughts.
