I am seeing traffic from my cell phone to the broadcast address that I
would like to block. I added a rule:
3220 deny udp from 9050 to any
It shows no packet ever match even though I see many logged by my catch-all
rule: 5999 deny log udp from any to any
ipfw: 5999 Deny UDP in via wlan0

Why is the 3220 rule not matching the packets I see logged by 3220?
