      Hi.  I have been hijacking this thread: https://forum.pfsense.org/index.php?topic=93293.0 for some time while trying to figure out why I can't seem to get igmpproxy working properly.

      For reference, I am running a fresh, full install of 2.2.4 on a 40gb HDD.  I was previously running 2.2.3 and 2.2.4 embedded on a 4GB CF card, but decided to go with the full install to try to rule out nanoBSD as a possible cause of the problems I've been having.  After much trial and error, I am still having problems.

      First, my igmpproxy.conf:

      ##------------------------------------------------------
## Enable Quickleave mode (Sends Leave instantly)
##------------------------------------------------------
quickleave
phyint em0 upstream ratelimit 0 threshold 1
altnet 224.0.0.0/4
altnet 184.60.0.0/16
altnet 184.61.0.0/16

phyint em1_vlan10 downstream ratelimit 0 threshold 1
altnet 10.10.0.0/24

phyint lagg0_vlan80 disabled
phyint lagg0_vlan10 disabled
phyint em1_vlan12 disabled
phyint em1_vlan80 disabled
phyint bridge2 disabled

      em0 is double natted behind my ISPs residential gateway for the moment, until I can get igmpproxy working properly on pfSense, and then replace the RG.  So, the IP address assigned to my WAN interface (192.168.0.2) is reserved from among the RG's DHCP range.

      em1_vlan10 is assigned to the LAN interface in pfSense.  I do not have the em1 port assigned to any interface in pfSense at the moment.  When I run "igmpproxy -d -v -v /tmp/igmpproxy.conf" from the console, I receive the following debug output, which in a nutshell, attempts to configure lo0 as the upstream interface.

There must be at least 2 Vif's where one is upstream

      I have tried assigning the port underlying my vlan port to an interface in pfSense.  When I do that, igmpproxy does create the upstream Vif (instead of failing, as above), but it creates it on em1, instead of em1_vlan.

      I haven't been able to pull the debug information for that scenario yet- for some reason, when I configured the interface in the GUI, I lost my remote connection to all of the machines behind the pfSense box.  I expected it to drop after it reapplied the filters, etc, but thought it would come back up after a short time.  Alas it has not.  So, I will have to try it and post results later.

      But, if anyone has any input as to why igmpproxy is trying to configure the loopback interface in the above scenario, I'd love to hear it.  I don't really see any reason why the above config should not work.

      Thanks in advance for any input.

        So, here is the debug results now that I have assigned em1 to the GUEST (OPT6) interface in pfSense.  igmpproxy is still stubbornly ignoring the em1_vlan interface and configuring the em1 interface, in spite of the fact that it acknowledges the "disabled" token for that interface.  I wish I knew how to step through the code, so I could at least try to figure this out on my own.

          Hi,
          did you (or anybody else) solve this issue in the meantime?

          I have more or less the same problem.
          Instead of connecting my WAN(re0_VLAN4)/LAN(re1) interfaces to the proxy, it uses apparently during the final BuildIfVc process other ones.
          The igmpproxy version is 0.1

          Any idea how to solve the issue would be very much appreciated.

          cyberax.

          My .conf:

phyint re1 downstream ratelimit 0 threshold 1

phyint re0_vlan4 upstream ratelimit 0 threshold 1
