I'm building a proof-of-concept for a customer using an internal satellite feed.

I'm trying to broadcast this out of the WAN side of the Vigor router (all legally licenced).

I can successfully open the multicast feed when VPN'd to the router, but cannot access from outside.

I have enabled RIP on the active LAN, IGMP proxy (although not sure if that's needed for publishing out), and have NAT from the external port of the router to the internal broadcast address.

Does anybody know if the Draytek Vigor is capable of publishing multicast feeds externally? I cannot find any multicast routing table on the configuration.

Thanks!
