pimd - doesn't appear to work

  • I want to just have any any traffic between my internal network segments.
    The pfSense box is running on vmware and the down stream switch doesn't have any IGMP config so in theory all multicast traffic should be been broadcast to all switch ports in the same vlan. I want pfSense to then forward all IGMP traffic to any receiver on any other vlan.

    I have IGMP proxy disabled and PIMD enabled

    I don't ever seem to have an entry in the Multicast routing table:

  • Hi @kmarston

    Have you tried enabling "Allow IP Options" on the network segments you wish to pass multicast traffic between?


    Also, after making PIMD configuration changes, you may need to clear (reset) your firewall states as well for them to properly go into effect.

    Hope this helps.
