      Hello all!

      First of all congratulations on this fine product! I did several tests in VmWare enviroment and will switch to pfSense :)
      I have just one question.

      I have PC with 4 NICs.

      1 –> WAN (PPPoE)
      2 --> LAN (192.168.10.0/24)
      3 --> OPT1
      4 --> OPT2

      I noticed that pfsense has IGMP proxy.
      Can I achieve that I can watch IPTV with host on LAN interface without whole segment being flooded with multicast traffic?
      Just that port which needs it?

      From provider modem I have 2 cables to pfsense.
      1 in WAN interface
      2 in OPT 1 interface (this is where I plug in providers STB for TV; multicast)

      Thanks for all replies guys!

        That depends on your switch - better ones only send the traffic out on ports where somebody is subscribed, others (usually cheaper ones) won't.

          Thanks for answer!

          But can I pass multicast traffic securely (port forwarding) from OPT1 to LAN, right?
          If I just plug in multicast link from modem to switch that is not OK…
          But from modem to OPT1 and filter to MC only to LAN that would be OK?

            Multicast is not related to ports, but to IPs - you can't "port forward" that kind of traffic.

            However, please read the fine documentation. I haven't done anything with multicast and pfSense myself.

              Yup but my provider uses port 5820 UDP to send multicast traffic.

              I successfully configured IGMP proxy and created firewall rule to allow UDP 5820 to my LAN from OPT1 iface (plugged directly into modem).
              And now I have passed MC traffic to my LAN and can watch IPTV (securely :)) on it!
              Yay!
