uh--no.  those rules might not even load.  "--log-prefix" specifies a
string to prefix the log entries in your syslog files.  my rules were
literal:

/usr/local/sbin/iptables -A FORWARD -j LOG --log-prefix "PRE QUEUE: "

...

/usr/local/sbin/iptables -A FORWARD -j LOG --log-prefix "POST QUEUE: "

so the entries in /var/log/messages will have the strings "PRE QUEUE: "
and "POST QUEUE: " in them for identification purposes.
