    136136  The following list of hints may help you design and debug your implementation more rapidly.

    156156  Note that the timeout-based nature of flow removal dictates that small connection limits will be quite limiting. Keep this in mind when testing your firewall!

    159159  You probably want to change the `rule` structure defined in function `add_rule` to add two members: `limit` and `count` to store the maximum number of active flows allowed and the current number of active flows. [[BR]]
    160160  You should also over-ride the function `flow_removed` to subtract `count` when-ever a flow rule expired. [[BR]]
     161  You might also set the idle_timeout to a smaller number (e.g., 30) so that you do not need to wait for too long before they get removed :-) [[BR]]
    161162  To verify your implementation, use `-P` option in iperf to add TCP flows.
