How can I open a TCP connection with a source IP
address that's not configured on the machine?

I've created a proxy (like Squid but for another
protocol), and I use ipfw fwd to get the client's
TCP connections to this proxy.

The problem is that the connections that the proxy
open have the source IP address of the machine where
the proxy is running on.

What I'd like to do is to use the IP address of the
client as the source IP address of connections opened
by the proxy for that client.

Any way to do this in FreeBSD 4 or 5?
