IGMPproxy not leaving multicast streams

[staticznld]

Hi,

Just updated to 20.7 everything looked perfect at first.
When looking in netdata i see huge bandwith usage on IPTV vlan.
It looks like the interface is not leaving the multicast iptv streams.

Reinstalled 20.1 load backup file and everything is fine!

[staticznld]

Just tried a clean install of OpnSense 20.7, imported config.
But still not leaving multicast groups on the IPTV upstream.

See attached screenshot opnsense.jpg

opnsense2.jpg is 20.1.9 with same config and also some channel zapping.

You are not the only one. Same thing happens here, continuous broadcast of 22mbit.

Of course I would like to contribute with a bug report or additional information but I haven’t got a clue where the issue is. Package, OS, or plugin...

[jpatriarca]

HI all. I see the same behavior as here. Usually, in any new OPNSense releases, igmpproxy would not be working as expected.

I can also confirm that only some streams works but most of them are broken in a couple of seconds. Looking forward with a solution for this issue.

Hi All,, facing same issue as mentioned in this topic within my setup. after upgrade iTV is consuming a lot data and at the end streams are disrupted. Could someone clarify if this issue is already addressed in a BUG report/ID?

Yes and sometime it is not joining IGMP until restart IGMP proxy.

On 20.1 it is fine

I can confirm the issue. Still investigating for a potential hint that leads to rc.

This is the output of igmpproxy during the event of a MC Group Leave Event:

However running tcpdump on pppoe0 shows, that the igmp leave message never passes the interface.

By the way - why can't I just rollback igmpproxy package like this?

Code: [Select]

Are you actually able to enable igmp proxy without it causing the system to hang?  If I enable the service, it causes my system to kernel panic on every boot until I remove the service package in single user mode.

Yes the system runs fine except for stuttering and errors with just a couple TV channels.

[thoho]

I have the same problem: IGMP streams do not terminate (With Telekom Magenta TV).
Everything else seems to work without problems (IGMP Proxy also starts without problems).

i downgraded to 20.1 (Reinstall with saved config).

[mnaim]

IGMP works, no kernel panics.
But I cant to subscribe to new channel or change channel without restarting IGMP service.
So I have to watch TV with remote control in one hand and OPNsense admin GUI in second

And of course no IGMP leave so I have brutal traffic > 300Mbit during watching TV.
