Assuming you have IPFIREWALLING enabled in your kernel, you can use ipfw's count parameter to help you out. To get this to work, you'll need to know certain things about your network - basically: ipfw count ip from your-network to not your-network ipfw count ip from not your-network to your-network (your-network is in form ip/bits, or ip:netmask) You can use "ipfw show" to show your usage since you last reset the counter - I recommend you use "ipfw show" in your daily cron, followed by a "ipfw zero", which will give you daily usage (you might miss a tiny bit between the ipfw show and zero, but I'm sure that's not likely to make a huge difference).
