[44net] Scanning traffic; How much does the gateway get?

Since taking on a BGP routed /24 several weeks ago I've occasionally watched my gateway firewall logs in realtime to get a sense of how much traffic I get from the Internet at large for my little section of the AMPRNet. I get an average of 2.7 packets a second in random scanning traffic. Scaling this up to the /8 that comprises AMPRNet, I surmise that the UCSD gateway must get something like 176k packets a second. Assuming an average SYN packet of 20 bytes, this is something like 283 gigabytes per day. Is that about right, Brian? -J
