When I did the tests I used a variant of following simple script [1]. There you can see that I only used a src port range. In an original paper I wrote for my company (announced here [2]) I did create rules that only matched IP addresses, the results were bad enough ;). Meanwhile I should revise the paper as quite a few things have been addressed since then: For example the performance issues with OpenBSD packet filtering have mostly been squashed. I didn't continue on that matter because I fell severely ill last autumn and first had to take care of that.
