Since the ipfw(8) manual page can be a little confusing for someone little
experience using pipes, try the following.

Let's say 1.2.3.4 is the IP address that you have your httpd running on, 
rule number 400 is where the piping is to placed, and dc0 is the network interface:

	ipfw pipe 1 config bw 128KBytes/s mask src-ip 1.2.3.4
	ipfw add 400 pipe 1 tcp from 1.2.3.4 80 to any out via dc0

You can also use address/masklen (ie. 1.2.3.4/24) in place of a single address if
you have your httpd running on multiple addresses.

I hope this gives you a good example.
