Rtmfp android to android not working

Question

I'm testing a small multiplayer app using rtmfp. The problem is it's not working when testing the app android to android. Only from PC to android device.
After testing a lot I tried using Cirrus. And got it working when I set groupspec.serverChannelEnabled = true. BUT I would prefer not using Cirrus but the rtmfp protocol alone. Here's part of the code:
nc = new NetConnection();
nc.addEventListener(NetStatusEvent.NET_STATUS, netStatus);
nc.connect("rtmfp:");
//nc.connect("rtmfp://p2p.rtmfp.net/***keyhere***/"); //use cirrus.
function netStatus(event:NetStatusEvent):void{
          switch(event.info.code){
  // The connection attempt succeeded
                    case "NetConnection.Connect.Success":
                              trace("setup group" );
                              setupGroup();
                              break;
                    // The NetGroup is successfully constructed and authorized to function.
                    case "NetGroup.Connect.Success":
                              // Do nothing
                              trace("connect success "+nc.nearID.toString());
                              break;
                    // A new group posting is received
                    // post received
        case "NetGroup.Posting.Notify":
             // post received
                   if (event.info.message.word) {
                               game_mc.okknap_mc.visible=true;
                      writtenWord= event.info.message.word
                       addThisWord(writtenWord);
                              break;
                  // routed message received
        case "NetGroup.SendTo.Notify":
           trace("notify received");
             break;
                    // user joins?
                    case "NetGroup.Neighbor.Connect":
                                trace("user joined "+ event.info.peerID.toString());
                    break;
function setupGroup():void {
          // Create a new Group Specifier object
          var groupspec:GroupSpecifier = new GroupSpecifier("testing");
          // Enable posting
          groupspec.postingEnabled = true;
          // Enable routing
    //groupspec.routingEnabled = true;
          groupspec.ipMulticastMemberUpdatesEnabled = true;
   //groupspec.serverChannelEnabled = true //it works with cirrus when I enable this. If not using cirrus it doesn't work even if this is enabled.
  // Causes the associated NetStream or NetGroup to join the specified IP multicast group and listen to the specified UDP port.
          groupspec.addIPMulticastAddress("225.225.0.1:30303");
          // Constructs a NetGroup on the specified NetConnection object and joins it to the group specified by groupspec.
          group = new NetGroup(nc,groupspec.groupspecWithAuthorizations());
          // Set the NET_STATUS event listener
          group.addEventListener(NetStatusEvent.NET_STATUS,netStatus);
function post2members():void {
var obj:Object = {};
                                        game_mc.okknap_mc.visible=false;
                                        // Set the peerID to a group address suitable for use with the sendToNearest() method.
                                        obj.sender = group.convertPeerIDToGroupAddress(nc.nearID);
                                        obj.word=writtenWord;
                                        obj.id = new Date().time;
                                        // Sends a message to all members of a group.
                                        group.post(obj);
