Driver issue can hide traffic from pcaps. The ix driver had a bug that was filtering vlan0 for example. pcap showed no traffic.
-
@stephenw10 ah - good info.. But that is a error at the driver level.. Not some software in pfsense.. But guess there could be a problem after he updated with the driver.. Good info!!
-
Of note is that the whole thing is a LAGG, and often packet captures do not function as one would expect. Several times in the past I have ended up having to run individual captures on the interfaces involved in the LAGG to get a complete picture.
If it were me, the first diagnostic thing I would do is to remove the LAGG from the picture. YMMV.
-
@dennypage also great info - and I have seen that in the past.. When troubleshooting where trying to validate traffic gets to where it is suppose to go and there is a lag at the endpoint, we have always turned down all but one interface in the lag

I restored a know working configuration from last year to my switch : it didn't solve the problem.
But by doing a packet capture on pfSense this time, after restoring my switch config, I have a weird behavior :
- First after restoring (and restarting) my switch config, everything was working, I asked a multicast IPTV stream from my ISP on my PC and I was able to receive the stream.
- But as soon as I stopped the stream, it stopped, but I was not able anymore to ask this multicast stream.
Here is the capture : as you can see, after packet n°10 with my PC leaving the multicast group, pfSense only see multicast from its own IP sourcecapture.pcap

You know who might be good resource - @bmeeks he handles all the IPS stuff, fairly sure he would know if something could prevent being seen at the sniff level in pfsense.
The only possible way for IPS to interfere with a traffic sniff would be when using Inline IPS Mode with the netmap kernel device. That could theoretically intercept and drop a packet before PCAP on the interface could see it, but I actually doubt that both PCAP and netmap can coexist simultaneously on the same physical interface. I suspect one of them is sure to complain about the other during initialization.
But simply stopping the IDS/IPS service is sufficient to completely remove it from any possible interference in the sniff.
-
By reseting the port link on my switch for my pfSense, I can reproduce this behavior
-
@bmeeks I tried a packet capture after stopping the dpinger service, but it didn't change anything.
I correct myself : on a capture on my pfSense when I have this problem, I only see multicast with IPv4 source address of my pfSense AND MDNS multicast packets (224.0.0.251) from my lan AND multicast leave group from my lan (but not multicast join group)

stopping the dpinger service
what would that have to do with anything - dpinger is what checks to see if your gateway is online via pinging it.
-
@johnpoz I though this would stop IDS/IPS service as said above
-
@maximushugus said in multicast inconsistant:

It won't. dpinger has no relationship to IDS/IPS.
-
I don't really know what you mean by IDS/IPS. If it's in relation to snort or suricata, i do not have those packet installed
I have wireguard, avahi, openvpn (and arping, iperf) -

I have wireguard, avahi, openvpn (and arping, iperf)If you do not have Snort or Suricata installed, then forget all the remarks about IDS/IPS. They are not relevant without one of those packages installed and running.

@maximushugus, you should start with this suggestion:
@johnpoz said in multicast inconsistant:

-
To update the topic : for the moment I'm not able to do testing disabling lag because of my configuration.
But I reinstalled pfSense 2.7.0 reimporting the exact same configuration, and my multicast is working again.
I suspect a bug in the igmpproxy program in pfSense 2.7.2 (or pfSense 2.7.1 but I never tried this version)
Maybe it is related with this : https://redmine.pfsense.org/issues/15043 -
@maximushugus said in multicast inconsistant:
https://redmine.pfsense.org/issues/15043
It could be that. Those fixes are in 24.03.
-
I tried to transfer the igmpproxy binary from working 2.7.0 pfSense to 2.7.2.
But it looks like the binary is exactly the same...To resume : if I restart my pfSense interfaces and launch igmpproxy, the first multicast stream I ask is working. But as soon as I leave this first asked multicast stream, it is not working anymore, and if I do a packet capture, I do not see any multicast packets exept those with IPv4 source address of my pfSense AND MDNS multicast packets (224.0.0.251) from my lan AND multicast leave group from my lan (but not multicast join group).
I managed to get igmpproxy logs from working state to not working (by restarting interfaces from my switch and lauching igmpproxy after reconnecting). On this log I put "****************" when I left the stream on my PC :

Because the igmpproxy binary was not changed, I think this is a kernel/pfSense issue with rule/state/filter table between 2.7.0 and 2.7.2,
What do you think about it ?
Thanks -
Also if it can help, here is netstat -g results at different moment during the problem :

Just to update, I still have the problem.
But I installed and properly configured PIMD, disabling IGMP proxy.With this configuration I have the exact same problem : I only see multicast with IPv4 source of my pfSense, and MDNS, (224.0.0.251) from my lan and multicast leave group but not multicast join group from my lan.
So I this the problem is in pfSense itself and not in IGMPproxy nor PIMD
Also if from a PC on my lan I ping a multicast 224.0.0.2, I can see this on a capture on pfSense.
That's really weird

I found I have the same problem as discribed here
I have the same configuration with a LAGG of ixl0 and ixl1
I suspect this is the problem.
I get a lot of those errorspfSense kernel: ixl1: Disabled multicast promiscuous modewhen enabling or disabling any multicast program (avahi, igmpproxy or pimd), even if I disable every program
