ipfw along with netstat

[Jordi Moles]

hi,

I've done a lot of research about that but found anything like i need. 
I'm running an ipfw firewall on a FreeBSD 6.1 and i wonder if ipfw can 
add rules automatically when it detects, for example, that an ip address 
has 100 connections open in the server. I'm doing a similar thing with a 
perl script and netstat. The script counts how many connections an ip 
address opened and it automatically adds a new rule to the firewall, but 
I'm looking for a way in which ipfw does that on its own.

thank you.
