Hi Pai,

I'd check the packet filter log to determine the nature of the attack.
Sometimes its false positive and sometimes its something worth worrying
about. Determine who's doing the scanning and then assess whether
they've done something similar in the past. Unless it's a repeat
offender, its probably not worth worrying about.

HTH,
Tom
