I cant get socket connection outside the server box

[David Mathews]

Thanks. I have finally gotten an outside connection by hostname. IP  
doesn't work, but since I'm on DHCP for ip I'm just dropping that part.

I have most of the app running, except - Can you use two different  
ports at the same time?
I need the two programs to listen on a different port, since I need  
to wait on a signel back that the current job is finished.

As soon as I add a listener to a different port on the server, all  
the previously running socket code fails.
If I listen to the same port as I use to connect out on, everything  
works, but it means I can't have a client running on the server box  
as it won't let me run two listeners on the same port.

Is the single port a wxSockets limitation?
or is there a way to set that up?

I really need to be able to run a client on the server box, since the  
server does nothing 99% of the time. It is just handing out jobs to run.

Thanks,
David
