I have a simple Client/Server program that functions as follows: Each client sends data (name and x/y coordinates) to the server. The server then sends all player data to each client. Each client then draws every player onto the screen (simplistic multiplayer game).
The program works flawlessly on my internal network, but if the clients use the 'public' IP the following occurs: The clients are able to send information to the server but unable to receive from the server (the receive call always shows the socket in a NotReady status).
This is the gist that shows the function call that ultimately fails (socket.receive):

EDIT: Forgot to include, but I have forwarded all ports utilized in my program (and tested using Port Forward Network Utilities and Simple Port Tester), and tried disabling my firewall on the computer I was testing on. This problem also persists if I run the server and client on separate computers (works on local network, but doesn't using the public IP).
EDIT2: Further clarification--when I mentioned that the client is able to still send information to the server; that is only true for the FIRST packet. All other packets seem to not transfer correctly (no errors that I can see, but just zeroes are received for the player's position each time). Again, this only happens when using the 'public' IP address.
