I don't see any reason why the link should go up on Netbios requests,
since we will block them on the incoming packet filters. However, note
the line above:

   ignore udp udp.source=udp.netbios-ns,udp.dest=udp.netbios-ns

which will also have some effect.

The next thing is to find out whether these are the cause of your link
going up - just because they _could_ being the link up, it doesn't mean
that they _are_. From your previous mail, you have machines fetching
virus patterns externally and they will also cause the link to go up.

That investigation, and the conclusions you reach, will depend on
your telephone charging regime - there is no one answer. This would
be a great devinfo project - a flexible set of diald filters which
catered for the various phone charging regimes.

If you have suggestions for improvements, please send them
to [EMAIL PROTECTED] along with evidence that it is a problem (i.e.
show the log entries which show the link up caused by packet type x).
