Hi,

Yes I was a little too quick with the passive interface comment ...
I once read this document:
http://www.cisco.com/en/US/tech/tk365/technologies_tech_note09186a0080093f0a.shtml

Where it was done with the distribute list ... but it got the
information from the passive interface guide ...from the link ... so I
was a little confused ;-)
Sorry bout that fella's
