On a related note then, It might be a good idea to expand the suppression syntax to allow joining 'track by_src' and 'track by_dst' in one statement. I use a lot of pass rules and suppression statements to limit FP without disabling the rule. I'm often reluctant to use a suppression statement, because what I really want to suppress is an alert to a specific address from a specific network, which I believe right now requires requires a pass rule.

Wally, This is a good question. Thanks for asking. Pass rules and Suppression are pretty much processed at the same time, however, suppression does not require rule ordering, so it's preferred your use Suppression.
