Hi Philippe,
For performance reason, the collector process does not include a filter engine.
So you need a kind of post process filter to do that. Current NfSen does not
support that out of the box.
A somewhat ugly hack would be to create a kind of second 'live' profile with
your filter applied. You could then expire
the original 'live' with a short time span.
Sorry for that.
