PIMD on 2.7.2-Release does not route multicast - IGMP Snooping Checksum error

@stephenw10

On VLC receiver side not video.

[stephenw10]

Ok What do you see logged?

Do you see states opened for traffic?

[viren_d_patel0]

@stephenw10

Setting is simple

WAN - Router - LAN ---- IGMPv3 Switch --- comp1
|-- comp2

Only one interface LAN enabled.

Here is the Log from PIMD.

Let me know I am doing testing right way.

So the server is comp2 in the WAN subnet and the client in comp1 in the LAN subnet?

The switch is a layer 2 device?

[viren_d_patel0]

@stephenw10

No it is connected on LAN. I try to draw but did not post it right.

[viren_d_patel0]

@stephenw10
yes

[viren_d_patel0]

@stephenw10
Grand stream GWN7803

[stephenw10]

Hmm both test machines are connected to LAN? They are both in the LAN subnet?

[viren_d_patel0]

@stephenw10
yes

[stephenw10]

Hmm, then they should be able to talk directly. That traffic does not go through pfSense so pimd wouldn't be doing anything.

[viren_d_patel0]

@stephenw10

Following test is with SINGLE LAN port.

Grandstream switch has IGMP V3. If you enable that it talks to router and supposed to connect based on IGMP reports. ( If router disabled PIMD switch control wiht out any problem )

It does work for few mins on single LAN connect but after few mins it gives error in Switch and Switch stop ccontrolling IGMP v3 trafic on that port with error.

My PC1 send multicast (SSM) three video 232.1.1.30 / 31 /32. PC2 receive no problem but after few sec it stops working.

PIMD status:

0 192.168.1.145 192.168.1 1 DISABLED

I have tried with LAN and OPT Today morning !

Not wokring !
Packet Capture attached as under.

packet capture.pcapng

Please see all the setting. Do my set up is right?

PC1 on OPT 10.10.1.0 network and receiver in LAN 10.0.0.0 network both is DHCP.

No Video on PC2. See all my seeting screen.

Random error in packets

[viren_d_patel0]

@viren_d_patel0

Forget attach last screen shot for OPT to LAN.

[stephenw10]

Hmm, well I'd expect it to work between hosts in the same subnet without an issue. If it fails that feels like a problem in the switch.

Why are you NATing traffic outbound on OPT?

[viren_d_patel0]

@stephenw10

Does it required for PIMD to work?
If any LAN device try to connect in OPT device.

[viren_d_patel0]

@stephenw10

Did you see packet capture? Randomly I do see error in packets.

[stephenw10]

@viren_d_patel0 said in PIMD on 2.7.2-Release does not route multicast - IGMP Snooping Checksum error:

Does it required for PIMD to work?
If any LAN device try to connect in OPT device.

Yes you would need PIMD or IGMPProxy to get multicast working between subnets on the router.

[viren_d_patel0]

@stephenw10

Thanks for quick reply.

Do you see any error in my set up?

Thanks again

Vic

[stephenw10]

Well I'm not sure why you have the outbound NAT rule on OPT. That shouldn't be required, everything there is routed.

But that test is not something I've done with PIMD. I have done it with IGMPProxy and it did work last time I tried it.
