Doing so does work well for me. But remember to secure the snort machine as much
as possible, because when the box is compromised there may be a "workaround" for
the firewall!

No IP for the "snorted" interface, use a receive only cable (see the FAQ 3.1 for
that) but be warned: It may not work with a switch!
