Here is a filter example...
Code:
D.Port=20-21
Protocol=tcp
Limit=6/h
Burst=5
Action=log


This example shows how the limit parameter and burst parameter affect the actions they are associated with. The first 5 packets with a destination port of 80 will activate this rule when the burst parameter is set to 5. After this it will be 10 minutes before another packet with a destination port of 20-21 will activate this rule due to the limit parameter being set at 6 per hour (1 every 10 minutes).

For every 10 minutes that go by without a packet whose destination port is 20-21, 1 of the burst counters will be regained. If 50 minutes go by and no packets are found with a destination port of 20-21 then the entire burst parameter of 5 is restored and 50 minutes would be considered the recharge time.

We recommend making a test using Syslog messages so that you can watch when a packet is caught in the filters.
