XDMCP Connection failed, try again [1]

I am trying to get x browser session from the x manager to host. Both are in different subnet.

I have checked the configuration & all is correct but still am getting this error

Program Ver. : Xmanager 3.0
Connect Method : XDMCP connection

In order to use XDMCP session, you need to

- Enable TCP port 6000-6010 on your PC
- Enable UDP port 177 on the remote host
- Remote host must be able make connection back to your PC

If your PC and Linux/UNIX machine are in different sub network, it is recommended that you use Xstart and run Gnome (or KDE) via SSH connection. This will save you the effort to reconfigure network settings and also add security. To start the desktop environment with Xstart over SSH, please follow the instruction in the following link:
