ipmon not logging correctly

Hello,
I've got a new fbsd 5.1 machine that is not logging ipmon output
correctly. Below are the relevant lines from /etc/syslog.conf,
/etc/newsyslog.conf and /etc/rc.conf,
Basically what's happening the ipmon output is being written to
/var/log/all.log which tells me that line is working, but i do not want it
to go there, i want ipmon output in ipf.log and although the files get
created they're blank for a majority of the day, the only thing they have in
them is a notation that newsyslog rotated them.if anyone can point me in the
right direction i'd appreciate it. This has worked before.
Thanks.
Dave.
