Back-channel multicast maintains a TCP control channel between the client and RealServer. The data stream is multicasted using UDP from the RealServer to RealPlayers who join this multicast group. Use this type of multicast when user authentication is required or you are multicasting to a medium sized group.

If you remove all Client Access Rules from the Back-Channel settings, RealServer automatically grants access to all multicast client IP addresses, and re-inserts the default Access Rule.
