      I won't even begin to pretend that I know what I'm doing.  My internet research has lead me to believe I can route multicast traffic with IGMP Proxy.  However when I try to assign the upstream interface to be my OpenVPN interface (ovpnc1), the logs show:

      igmpproxy: ERRO: There must be at least 2 Vif's where one is upstream. (vifcount 2, upStreamVif -1)
      

      I've assigned my ovpnc1 to an OPT interface to be able to assign IGMP Proxy upstream to it to begin with.

      My igmpproxy.conf is as follows:

      
      ##------------------------------------------------------
      ## Enable Quickleave mode (Sends Leave instantly)
      ##------------------------------------------------------
      quickleave
      phyint ovpnc1 upstream ratelimit 0 threshold 1
      altnet 10.9.0.0/24
      altnet 192.168.254.0/24
      
      phyint vr0 downstream ratelimit 0 threshold 1
      altnet 10.9.0.0/24
      altnet 192.168.254.0/24
      
      phyint vr1 disabled
      
      

      Is this even possible or am I doing something totally stupid that won't ever work?

        Just to add more info and get a bump:

        Basically what I'm trying to do is get multicast traffic through a site-to-site OpenVPN tunnel so that some remote 3com NBX VoIP phones work fully.  Without the multicast they lose some slight functionality; in-use lights, intercom, conferencing.

        Can someone give me an idea if I'm even going in the right direction here?

          Yes this does work.
          I used this to stream media via a VPN to a PS3.

          Fram what i can read in your config: Did you configure the same subnets on both interfaces?
          You can only have one(or multiple) subnet(s) upstream and one(or multiple) subnets downstream.
          But not the same subnet up and downstream.

          We do what we must, because we can.
