    you need people to look at the logs :)

    I use ipaudit-web
    for looking at realtime traffic, snort for IDS behind the FW , modular syslog to log to a mySQL server in addition to flatfile syslog
    on the server.

    The ipaudit is excellent, I just caught a virus flooding UDP port 137
    outbound and squashed it. (unfortunately I can't lock the host up to
    prevent the user from shutting off virus protection at the moment)

    Snort is good but you will get alot of false alarms that if given to
    your customer will cause panic. Which might be a good thing but be sure
    to get paid by the hour not the job, so when they call you can charge
    them. :)

    msyslog has worked really well to examine the logs through a php web
    interface. this will enable you or your customer to see if ports are
    blocked by source or destination and make the appropriate changes.

    the flatfile syslog is good just for your own records. I rotate mine
    daily and gzip them to save on space, later zcat to view them.

    you can give them all sorts of fancy interfaces but you will still have
    to have someone sort through the data. Unless I'm wrong which I hope I
    am and someone on this list gives me/us an alternative. :)

    btw, if you need the dsl config for the pix, post to the list and I'll
    cut and paste mine. both dynamic and static configs. cisco is also
    coming out with a NAT/PAT IPSec pass through in the next version (6.3).
    I'm trying to get the beta now from my rep. to test it.

    best of luck to you.
