ipmon logging

[as2sb3100 at comcast.net]

According to every website I've read so far ipmon uses local0 as the facility name.  However, on my FreeBSD 5.3-RELEASE-p5 box, it logs to the security facility.  The man page (in both 5.2.1 and 5.3) for ipmon, with -s for logging to syslog says, "The default facility when compiled and installed is security".  Can anyone explain this?  I'd like ipmon to log to a separate file so it doesn't fill up the security log.  I've tried having ipmon log directly to a file, and not using syslog, but it stops logging when newsyslog rotates the file.  Does anyone have any suggestions on what I could or should do?
