Xbee Wifi - Server PHP not Recieved

Hi guys!
I have an X-bee Wifi and would like to make a communication between a server php and Xbee. I do a consigue ClientTCP send data to the Xbee, but can not send data xbee to the server.

I tested with the UDP protocol and the same thing happened. When I make a communication server / client UDP data flow correctly, when I use the xbee to send to the server does not happen anything.

Someone went through this problem?
