I increased the maximum packet count when I was testing the throughput on my switches. If you add a rule at the end to allow the discard packets, you should be able to acess the maximum throughput you can get in a worst case situation. I would suggest you do your initial test without routing, to get some idea of how that compares to the routed and filtered tests. Tim.
