Too bad. I realize this happens on ppp level, where IP filtering is
not able to kill the beast.

Ummm, I´m out of my depth here: looking at /var/log/ppp.log, some data 
scrolls by. After that, the idle timer gets reset. I included the data 
for your reference.

Maybe there is other data hidden in there as well -- I cannot
say.

Thanks for your fast response

P.S: I leave town for the weekend, so if I should look for anything else,
please be patient -- I´ll be back Tuesday evening.
