routing multicast traffic

Please help me!I've got a linksys wrt54g router(which is a linux machine)
with wifibox firmware, when the router is reached by a multicast stream
(from outside) it doesn't forward it to che
clients connected to it... how do I leave the UDP multicast reach the
clients
connected to the router?here is my configuration:
# route

Hi,

Does not surprise me, why should it? It does not run a multicast routing
daemon such as mrouted, pimd or XORP. Just because it is able to route
unicast traffic does not necessarily mean it can do that with multicast
traffic as well. You could setup static multicast routes with tools such
as smcroute though.
