Multicast paging being blocked between two Lan Interfaces



  • Pfsense Ver 2.2-Release
    I have a Voip phone system which uses multicast paging on ip/port 224.0.0.1:3333
    I have two lan interfaces on the pfsense
    Lan1 192.168.1.0/24
    Lan2 192.168.3.0/24
    Both lans can see to each other and all functions of my phones and network are working with the exception of multicast between the two lans.
    I have also setup IGMP proxy with the following
    UPstream
    Lan 1
    Value 192.168.0.0/24

    Downstream
    Lan2
    Value 192.168.3.0/24
    I have also tried different combinations of adding the 224.0.0.0/24 to the up or downstream values without success
    I am new to this so any help would be great
    Thanks



  • I had a similar problem. I tracked it down by observing tcpdump and the pfSense logs.


  • LAYER 8 Netgate

    Lan1 192.168.1.0/24
    Lan2 192.168.3.0/24
    UPstream
    Lan 1
    Value 192.168.0.0/24

    I guess I don't understand why the Upstream isn't 192.168.1.0/24



  • Sorry I made a typo
    My Lan 1 interface is 192.168.0.0/24
    My Lan 2 interface is 192.168.3.0/24

    The 192.168.1.0/24 range is in use on a VPN that is not related to this
    Unless you think it makes a difference?
    Thanks for the response I'm still having trouble getting this to work
