IGMP proxy no longer works reliably after 2.7.1 update

vjizzle

The previous version for me was pf+ 23.05.01 and igmp was functioning fine. With all the changes to the license model I decided to go back to pf CE 2.7. And now back to 2.6 because of igmp bug. If pf+ get's the igmp fix before 2.7 I am jumping the wagon to pf+ again :)

mistergefahrensucher

Same here in PF+

will give a try to extract the working version from 2.7.0

@mistergefahrensucher sorry i meen PF+ 23.05

@mistergefahrensucher sorry i meen PF+ 23.05

Please keep us posted, I'm craving for a solution. I even tought my wife to log into the firewall to reset igmp herself

@mistergefahrensucher

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.

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

@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.

@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

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

@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

@michmoor

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

UlfMerbold

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

@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

@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.

@vjizzle

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

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

@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......
