Hi There, I could be wrong, but I don't think simple Multicast Routing will accomplish this. This is almost more of a protocol forwarding option, like DHCP forwarding. I haven't done research on this, but I would first google to see if there is a way of accomplishing this with a normal router. If it can be done by configuring Multicast in a certain way then we may be able to do it on the firewall using standard Multicast configuration. If not, broadcasting ATV traffic across L3 boundaries may take some type of proprietary solution, such as protocol (bonjour?) forwarding. Note, that there is a reason why these protocols have broadcast-domain scope - they can be quite chatty, so it may not be in your best interest to break that model. Cheers, Kelly
