Android <----------------------------------------> router <-----------------------------------------> Server

My issue is that when I set up port forwarding and such on my router, my computer thinks that my android is the router. I need to know what IP address to reply too. This is my recieving code (UDP library):public void receive(byte[] data, String ip, int port) {  

2. public void receive(byte[] data, String ip, int port) {
3.   datastr = join(str(char(data)), "");
4.   println("Recieved Data From: " + ip + ":" + port + " Data: " + datastr);
5.   if(datastr.substring(0,1).equals("MR")) {
6.     storeMessage(datastr.substring(2, datastr.length()));
7.   }
8. }

When I receive a message, I get my printout that says "Recieved Data From: 192.168.1.1:2001 Data: <data>". But that isn't the IP address of the android phone. That is the IP of the router. How to I know where to send the message back to?
