Newbie syslog question

[trinli]

I have two lines in my log which are exactly the same, except for one thing:

pf: 13. 869250 rule 37/0(match): …

and

pf: 056470 rule 37/0(match): ...

They appear in this order, and one is directly after the other in the log.  I'm not sure what these are telling me.  What are the numbers right after the pf, and why is one pf: #. <something>and the other is just pf: <something>?  They both match rule #37 right?  And, what does the zero after the "/" mean, and does it ever change?

If anyone has some knowledge on this, please share.  I've run a google search as well as searching this forum, and haven't found the answer.

Thanks.</something></something>
