Subject: Basic load balancing with IPFW

I've been googling and reading man pages all morning, and I can't find
out if I can do some very basic load balancing with IPFW.

Basically, I have four servers with the exact same config. I want to
equally (or not) distribute traffic across them. Suppose I get 200
connections, I'd want to be able to distribute them like so :

Server1 : 50 connections
Server2 : 50 connections
Server3 : 50 connections
Server4 : 50 connections

Or,


Server1 : 80 connections
Server2 : 20 connections
Server3 : 50 connections
Server4 : 50 connections

And so on. I can't really cluster the machine themselves (actually, I
can't touch them at all). I'm *thinking* that this is done at the
firewall level, since the Linux box that currently does this job does it
with IPChains. Actually, as long as I can 'round robin' or 'ration' my
traffic across those 4 servers from a IPFW gateway, I'll be happy.

Thanks in advance for any info.
