From the man page,
The ipfw code works by going through the rule-list for each packet
until a match is found. All rules have two associated counters, a packet
count and a byte count. These counters are updated when a packet matches
the rule.
So, if you have any rules before the above two, it will not be counted.
You might get what you need simply by looking at netstat -ni
