May be /usr/ports/sysutils/ipa is the answer to your problem. Quote from port description:
ipa(8) allows to make IP accounting (network accounting) based on FreeBSD IPv4/v6 Firewall (including IPFW2), OpenBSD Packet Filter and IP Filter accounting rules on FreeBSD, NetBSD and OpenBSD. It supports limits for accounting rules and limits events as "limit is reached", "reached limit is expired", etc. It understands time intervals like "end of day", "end of week", "end of month", etc. ipastat(8) is a viewer for IP accounting database made by ipa(8).
