It depends on how you have Portsentry configured. There are provisions for
an ignore file to add addresses not to trigger on. The risk is someone
could block some legitimate users by spoofing their addresses. I have to
disagree with the statement that portsentry is "crap". It is a different
animal than snort and I believe I have a place for both in my network.

Having 'reactive capabilities'
