IGMP proxy no longer works reliably after 2.7.1 update

Remie2000 · Dec 5, 2023, 6:07 PM

I've also created a separate bug report for the PF+ version to get it on the bug tracker of PFsense+.

You can find it here (https://redmine.pfsense.org/issues/15065) , there is a big chance it will be merged with the 2.7.1 bug report.

It would really help to also share your logs and other findings there to help the developers fix this issue.

@Remie2000

i will do my best. But i can't find the log. My knowledge is to small.
I have enabled verbose logging in IGMPProxy but i don't know where i can find the results.
Are they normally came in system Log -> general ?
Just right now i noticed the:
/usr/local/etc/igmpproxy.conf
is empty (looks like a copy from default). Is this right ?
I expected to see the things i have configured on the web GUI

mistergefahrensucher · Dec 5, 2023, 6:32 PM

@Remie2000
ok i found my /var/etc/igmpproxy.conf
this was working with 23.05 and now after some time it stops on one chanal.
Not always the same but when i restart the igmpproxy it work for some time.

@mistergefahrensucher Thanks a lot for your feedback.

ninin06 · Dec 5, 2023, 7:47 PM

@Remie2000
Your ticket has been added to mine and the target version has been set to 2.8.0 and 24.03.
https://redmine.pfsense.org/issues/15043

I now hope that these versions will be released as soon as possible.

vjizzle · Dec 5, 2023, 8:50 PM

Release 24.03…wow. So the fix is targeted to be here somewhere in the next 6 months orso?

Is it possible to run the igmp proxy package from 2.6 on 2.7? That would be a workaround perhaps for the time being.

michmoor · Dec 5, 2023, 9:00 PM

@vjizzle
Release fixes are estimations not hard deadlines. It could theoretically be pushed back for months or years so ive seen.
My advice, If possible, downgrade back to a working pfsense version. Not great advice i grant you but i dont know another solution.

Also i advice people on the following
https://www.netgate.com/supported-pfsense-plus-packages

vjizzle · Dec 5, 2023, 9:41 PM

@michmoor

Thanks. I already downgraded tot pfsense 2.6 where everything is working fine. Now I will play the waiting game yes.

UlfMerbold · Dec 6, 2023, 7:21 AM

My Workaround is far more simple

Just set an cronjob for a time in the morning hours and stay at the CE2.7.1

	/usr/local/sbin/pfSsh.php playback svc restart igmpproxy

This fixes it for the day in my setup

mistergefahrensucher · Dec 6, 2023, 8:55 AM

@UlfMerbold

i have done this but in my case it's doesn't help.
These reason is if you change to often between 2 chanals in short time the proxy get messed up.
I will try to install the older working igmproxy

mistergefahrensucher · Dec 6, 2023, 9:00 AM

@vjizzle

can you help me please how to install the older package ?

Restarting the igmp proxy works temporarily, but it happens again when changing channels a few times so not really a workable solution here.

I have not installed the older package, I just downgraded to pfsense 2.6 where igmp works fine. I also would like to know if it is possible to install the igmp package from 2.6 on 2.7.

UlfMerbold · Dec 6, 2023, 4:24 PM

Since we are now at FreeBSD 14 i do'nt know if an install from an different Kernelversion works :/

There must be a "newer" Version of igmpproxy (4.1.1), we should be on 4.1 originally on pfsense

But since the versioning is a bit unloved by the maintainer, i dont know it fixes something from our mess...i'm not an programmer and while looking at the changes last two years, i've no clue what the problem is exactly

Link Text Freshports says there is an new version

Link Text FreeBSD Org too..

But dont see any link to the package?

the "normal" way to install would be

pkg add -f "link to the repo"file.txz

But as i sayed, i did'nt find any FreeBSD 14 Repo from

Rai80 · Dec 6, 2023, 4:24 PM

@UlfMerbold I tried 4.1.1 and also older versions 3.x.x. None of them work. So it seems its not the IGMPproxy software but something in the kernel/freebsd release.

If you want to try you can enable the FreeBSD repositories by changing the value from no to yes in /usr/local/etc/pkg/repos/pfSense.conf and /usr/local/etc/pkg/repos/FreeBSD.conf

pkg update
pkg search igmpproxy
pkg install igmpproxy......

mistergefahrensucher · Dec 7, 2023, 10:27 AM

@Rai80

thanks for testing.
At the moment i have another workaround (somthing from the past as IGMPProxy also not worked)
I configured a servicewathdog. Last 2 Days have seen 2 restarts in the morningtime.
This worked for me so far.
But indeed there must be somthing wrong the combination new Kernel and Proxy.
If you said 0.31 ist also not working. i noticed 0.31 is the former version working with Kernel 14 from PF+ 23.05.
So the Kernelnumber is matching. Look like someting is wrong with checksum and lost IGMP memberships. And when you heavy switch betreen 2 chanels there is a memory leak or what else. (i'm not an expert on that level)
Someting has changed in the new 14 Kernel.

If i find the time i will also tryout 0.31. and 0.4.1

or i will wait for a solution

mistergefahrensucher · Dec 7, 2023, 9:52 PM

@Rai80 said in IGMP proxy no longer works reliably after 2.7.1 update:

pkg update

gives error:

pkg: Error extracting the archive: 'Write error'
pkg: No signature found
Unable to update repository FreeBSD

what i'm doing wrong?

vjizzle · Dec 8, 2023, 9:02 AM

I just saw the new releases for CE and pf+ but sadly no igmp proxy fix in the release notes.

mistergefahrensucher · Dec 8, 2023, 9:02 AM

@vjizzle

yes but maybe a kernel fix ?
I think igmpproxy is not the problem because the same version igmpproxy is working fine with older 14er Kernel.
i see this:
