IGMP proxy and Multicast/broadcast.



  • Hey group.
    I'm trying to get a pfsense box to relay broadcast traffic from my LAN zone 192.168.10.0 to my VPN zone 10.0.8.0
    I got amongst other things a media portal server on my LAN and I want it to be able to send TV signal to clients on my VPN zone.
    but I can't seem to get it right, I have tried to make various combinations of upload and download interfaces and subnet addresses in IGMP Proxy settings in pfsense web interface. Can anyone point me in the right direction?
    Other than the right settings in IGMP Proxy, do I  also need some fw rules? I got "all to all allow in LAN to/from VPN"
    Best regards from Denmark

  • If you will need the IGMPv3 proxy, it is broken in the version 2.3.x with no fix for it.
    In the version 2.4.0 the IGMPv3 proxy works out od the box, there are some problems with the VLAN labeling.
    In the version 2.4.1 the IGMPv3 proxy works out of the box but VLANs over the WAN port and PPP are not working proper.

    So you might be using or trying out an early version of the 2.4.2 where all is fixed and fine running.
