Can you not configure the loop back w/ the address then bind to it and connect to the forgein end ? It's not exactly what you want, but I think its a game some apps play.

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?
