Multicast settings



  • Hello

    I'm lost on this topic.

    I've got a camera on synology surveillance station.
    The cam is set on multicast streaming
    GRoup 238.84.192.6
    video port 63370 ~ 63371

    The synology got ip: 192.168.0.100

    I'm unable to watch the live stream through surveillance station if set on multicast.

    On pfsense the rules are:

    IPv4 IGMP * * 238.84.192.6 * * none
    IPv4 IGMP * * 192.168.0.100 * * none

    What am I doing wrong ?
    :o

    Thanks for help

    pfsense has nothing to do with multicast of devices on the same layer 2 network..

    how do your devices actually connect to the network, switch, wifi?  Are you blocking multicast at your switch?  Is one of your devices wifi and the other wired? etc..



  • Sorry

    I don't understand

    Thanks for explenation  :o

    you don't understand how your devices are connected to your network?  Are they wired or wifi, are they connected to interfaces on your pfsense box?  A switch, how are they connected??

    You don't understand what a layer 2 network is??



  • That I understand

    This cam is wired in POE with Dlink manageable poe switch.
    This switch is wired to cisco manageable switch
    Wired to pfsense on LAN network

    where are you??  trying to access this cam?  If your on the same network then pfsense has ZERO to do with anything on that network be it unicast or multicast…. Pfsense is a ROUTER it routes traffic off a layer 3 network to another layer 3 network..  And firewalls what traffic can go between these different network. It does nothing with multicast traffic unless your devices are connected to different networks on pfsense and your wanting to use the igmp proxy.. Pfsense has nothing to do with your problem..

    My guess if your having problems wold be your switches are doing igmp snooping or filtering and that is what is issue.



  • There is stricly no issue accessing this cam on the LAN network.

    I want to access it on wan …
    It's not possible if I understand ?

    Thank for your time  :D

    you want to access from outside your network using multicast.. How do you expect that to work??  If you want to access the cam from outside your network then you would use port forwarding to the IP of the cam or the dvr/server that talks to the cam for its video etc.. using Port forwarding and an unicast address… Not multicast..

    I personally would not suggest you open a cam to the public internet..  If you want to view cameras from away from your network, then vpn into your network would be what I would suggest.  if your going to open it up to the public internet - Can you lock it down to source IP?  So that say you only ever access the cameras from work location or something.

    Opening up cameras to the public internet is NOT a good idea..



  • Sorry for that dumb question

    So Multicast is no go outside the LAN ?
    Without multicast I have access without a glitch as other services.

    I'm dumb on multicast

    Thanks

    Is your "wan" just another segment in your network, or when you say wan do you mean the public internet?

    multicast is not something you use over the public internet no..



  • OK
    i'ts for public so it's dumb

    ::)

    If you want to access your cam from the public internet then you would use your public IP, ie your unicast address..  And port forward whatever port your cam is streaming video on or your server that lists your cameras, etc.. Multicast has nothing to do with it.



  • I'm already accessing other cam that are not multicast compatible that way

    Thanks :)
