gprs gateway: why I can't connect to my server?

I am developing android phone application, communicate with my server. My server program listens on port 9999. If I use the wifi connection, everything is fine, but if I switch to GPRS connection, the client can't reach the server.

By tcpdumping the packet, I found when GPRS is enabled, every packet goes to the GPRS gateway with 80 port.

I am wondering what I should do to make my client be able to reach 9999 port of my server in GPRS case?

Can your server be reached by its IP? Try to connect to it with IP:port pair, where you specify desired port
