Das gilt nur fuer dynamisch vergebene IPs !

das ist  /etc/ppp/ip-up, die muss vorhanden sein, die Rechte 755 und
root:root gehoeren. Dann machst noch im Verzeichnis ein
ln -sf ip-up ip-down
Als $IFCONFIG_* musst Deine definierte einsetzen !

# If this machine is a server, force authentication by uncommenting one

#               On small systems, this file can be used instead of a
#               "named" name server.  Just add the names, addresses
#               and any aliases to this file...
