Description:
ISA Server detected an all port scan attack from Internet Protocol (IP) address 216.250.24.64.

Not much lee-way on the port scan option anyway as it is a global setting. On for everytghing or off for everything.

I do not believe you have an option to amend the entry in the log either though fir the same reason. In the logging section it is the same - log all or log nonce - there is no criteria, system key, script or the like that will let you select an exception.

In 2006 you get a new set of options in the configuration - general section (don't recall if 2004 had it or not) called flood mitigation. In here you could put mitigators fir a number of things but i still do not thing it would cover a spread of ports requests.

Sorry - the answer is No.
