XDMCP not working in ubuntu 12.04. Help.


I have enabled xdmcp in ubuntu 12.04.2 and this is the line from lightdm.conf

Code:
#cat /etc/lightdm/lightdm.conf

[SeatDefaults]
greeter-session=unity-greeter
user-session=ubuntu
autologin-user=
[XDMCPServer]
enabled=true
I have rebooted the ubuntu desktop. I have installed xcygwin in my windows 7 desktop. Now when i do a xlunch and try a xdmcp login, it gives me blank screen. I tried launching xserver and from terminal when i do a ssh -Y ashwin@192.168.2.3 and login and launch a X application, i can see the remote application on local display. So xserver on remote and local is working fine. So something is blocking. IS there any firewall changes i have to make or configuration setting i have to change ?

XDMCP uses TCP, UDP port 177 and TCP port 6000 to 6005
