you can use limit for that. here is the part about limit in ipfw manual:
limit {src-addr | src-port | dst-addr | dst-port} N
The firewall will only allow N connections with the same set of
parameters as specified in the rule. One or more of source and
destination addresses and ports can be specified.
so a simple way to limit max connections per ip is:
ipfw add allow ip from any to any limit src-addr 100
this way you will limiit yourself also with 100 connections per ip, but you
can play around with recv, xmit, via and other settings to fit your needs

Subject: ipfw along with netstat
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.
