Multicast IPTV on LAN



  • 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!
