Several user's replied citing resource problems doing this. However, nobody
mentioned the obvious that every firewall admin should know.

SECURITY matters.

Never run any network applications on your firewall box. No mailservers,
webservers, dns servers, and not snort either.

Why? Because if someone exploits snort (ie: the old stream4 vulnerability),
or any other program on your firewall box, they now have control of your
firewall machine. At that point, you have no firewall at all.

You really should treat a firewall box as a firewall-only system if you
want it protect you in the event of an attack. Severs, IDS's, etc are best
placed on other boxes so that an exploit of one doesn't bring the entire
security of your network down as a hacker digs your firewall apart from the
inside out.
