Changing the data and control addresses for mcast worked!! Thanks for all you time! One more question... is it necessary to change both the data and control addresses? Also, i only changed the addresses and left the port the same. Is this standard or is it more usual to see the port number changed and the address left the same? Thanks for the help!
