I'm a bit of a noobie, so you will have to bear with me (well, you don't but I'd appreciate it). I have three 2811 routers connecting three remote sites to the main network at my location. Currently, the remote sites are broadcasting data to UDP ports 3000-3200 where each data source gets its own port. The routers are set up to take the broadcast traffic and turn it into multicast traffic using the "ip multicast helper-map" command. Other than that, there is nothing exotic about the configuration.
What I would like to do is map each UDP port to its own multicast address in the 239.192.1.XXX range. It looks like I might be able to do this with static NAT, but it seems like a kludge to me. One other kink is that each source IP can transmit up to 3 different data streams AND data streams may be associated with multiple IP addresses.
Has anyone else run into a situation like this or does anyone have any idea how to do what I'm describing. Thanks in advance.
