IGMP Proxy issues



  • pfSense 2.3.1_5

    On my home network I have multiple LANs:

    • LAN: 192.168.1.0/24
    • LAN2: 192.168.5.0/24

    I have a DLNA server (Plex) on LAN2 and I would like it to be discovered and accessible by DLNA clients on LAN. Using the native Plex app everything works, but I would like to be able to use DLNA.

    I enabled IGMP Proxy as follow:

    • Upstream (LAN2) 192.168.5.0/24
    • Downstream (LAN) 192.168.1.0/24

    Note: I also tried the opposite with same results

    FW rules:

    LAN (DLNA clients)

    Allow
    IPV4
    IGMP
    from any
    to any
    Allow packets with IP Options

    Allow
    IPV4
    UDP
    from any
    to any
    dest. port 1900
    Allow packets with IP Options

    Note: LAN also has full unrestricted access to LAN2

    LAN2 (DLNA server)

    Allow
    IPV4
    IGMP
    from any
    to any
    Allow packets with IP Options

    Allow
    IPV4
    UDP
    from any
    to any
    dest. port 1900
    Allow packets with IP Options

    Clients in LAN are unable to discover to the server in LAN2. In the FW logs I see the rules are triggered and in the igmpproxy logs I see clients joining and leaving groups, but clients and server are not talking to each other.

    I searched this board and online and I found many similar threads, but never a conclusive answer on this topic.
    Any suggestion?
    Thanks.



  • I'm also using a "smart switch" Netgear GS108T v2 which has many options for IGMP snooping. Is it necessary to configure any of that on the switch or should pfSense be able to handle it regardless of the switch used?



  • Hi.

    People does not use igmp proxy to much, most of the topics have one post. I search for IGPM to find if it works with VLans in certain conditions in 2.3.1.

    Thank you. Unfortunately, after lots of testing and searching I just gave up on the idea to get it working.



  • I read this before but is a problem with 2.3.x https://redmine.pfsense.org/issues/6099#change-27787 an IGMP v3. If you want test something you should use the 2.2.6 even if this look like not affect you is suppose to affect vlan configs only. The number of time i try put some IPTV working i fail at least with the 2.3.x.
