    Did you see the reply to your earlier, similar, post here: http://forums.petri.com/showthread.php?t=22464

    Can you just have one list of what you want to block (or would it be quicker to have a list of what you want to allow? )

      I don't know anything about ISA but from as for firewalls and software restrictions it's much easier and much more secure to adopt a whitelist approach as opposed to a blacklist approach. This is how firewalls inherently work: what is not explicitly allowed is denied.
