To have an ip from zonealarm someone trying to scann ur ports etc.. And you sending messages to him through ip that would Own.
I can see three problems:

1. You will have just cancelled your Zonealarm stealthing, by telling the attacker that there is a computer at that address

2. I would guess that at least 70% of the attacks are from malware programs on compromised machines, which may well be servers, so you are not likely to get many replies?...........Bots are not very responsive?

3. The best you can do is use the "abuse" reporting facility of their ISP, but I am very doubtful if most pay much attention to complaints from private individuals, or to isolated incidences?

I am sorry, but that is the way things are
