Go through the network activity logs, and estimate the average no of packets per unit time that you consider as normal to your packet. 2. Then think of a tolerance margin. 3. Write appropriate rules for limting the rate of packets. I would recommend genarating a cron job that estimates the average number of packets per unit time after every day, and update the rule in filter table. Again optimal estimation is not a trivial job as it depends on several factors.
