Yes, but then you'd be using the same connection as well. I thought you
said you didn't want to do that.

I don't know of any way to accept a connection on the same port that you
originate connections from.

In that case, you don't want the server to make a connection to the
client. Odds are, the client will never receive it do to NAT, firewalls, and
the like.

Don't think about ports, think about connections. You have a connection
to the server. Have the server make a connection to the client the same way
the client made one to the server. However, be aware that many client
machines on the Internet cannot accept incoming connections.

I could probably help a lot more if you told me more about your
application. For example, is this one client on a machine that's connected
to the Internet the way servers are? Or is it a typical Internet client
machine?
