udp multicast listener not working

See more:

C#

I am trying to receive data from nse broadcast. I declared socket,endpoint then joined to group and port specified for nse future data but it failed to receive any data in any form.
Then I joined to another multicast group to listen multicast message sent by my test sender application. This time it works.

Since the testing computer has more than 1 LAN card I am mentioning specific IP to receive data.
I have seen here some of you already achieved receiving broadcast data from nse. I need your advice friends.

Kindly help to solve this...
