We've run a pentest against a customer recently and found that the very act of port scanning their Raptor firewall (running on NT) crippled its ability to accept incoming connections for their web site. The firewall is a new high spec PIII and the least line is a decent size. The nmap scans were standard timing (not T5 or anything daft) - once the scans were stopped, things burst back in to life within about 10minutes.
I experienced similar issues when scanning hosts behind a client's Watchguard firewall. I (together with some help from this list) put it down to built-in automatic IDS/blackholing of "naughty" hosts. I tried to get the client to disable the functionality, but either it isn't possible to disable completely, or... I've never (knowingly) managed to break a Raptor FW in this way - usually all I see is the same open port profile for all hosts and looking to the world like some strange cross between NT and some flavour of UNIX. :)
