The bind() API can be used to force a TCP socket to use a particular IP
address, as Michael already explained. Set the port to 0 to let the OS
choose the port.
However, this doesn't make sense to do. IF your TCP/IP routes are
configured properly, it will automatically pick the correct IP address.
If the routes aren't configured properly, binding to a particular
address won't help you, because the packets still need to be routed
correctly for the connection to work.
So this doesn't make a lot of sense to me.
Binding to a particular IP address is a tool usually used on a listening
server program so that you can (for example) listen on your internal
subnet without allowing access from the public internet. Stuff like
that. It doesn't make sense to use in a client program -- at least not
in my experience.
I wonder if you don't have a misconfigured route somewhere?

Using Scott Klement's socket utilities service program, I have created
working client and server programs.
Here is my dilemma - our network folks established a secure connection
(tunnel?) between us and another system. The problem is that the one
socket programs is now using the "other" ip address on our 400.the
Consequently, this program cannot connect!
So, my question is - Is there a way to specify the outbound IP address
socket uses?
Thanks,
