[OPNsense v26.1.10] IGMPProxy: MRT_DEL_MFC; Errno(49): Can't assign requested ad

[FvdAa]

Hi,

Since I updated OPNsense to v26.1.10 I'm experiencing issues with IGMPProxy and my KPN Interactive TV.

After a while, it seems that certain actions, f.e. starting an earlier recorded video is not possible and return and error (STB-zap-06) and when restarting the STB it hangs at 85% while starting up. When I then restart IGMPProxy, it directly proceeds the startup and I can also play the recorded video again.

Looking at the logs I can see the following warnings:
 - select() failure; Errno(4): Interrupted system call
 - MRT_DEL_MFC; Errno(49): Can't assign requested address

So far, this seems to happen every 3 days (23rd, 26th and 29th of June).

I found an older topic that looks like similar problem, also with IGMPProxy and KPN:
https://forum.opnsense.org/index.php?topic=41719.45

Anything to check the next time I encounter this issue?

Regards,

Frank

Consider moving IPTV away from OPNsense and offloading it to a dedicated device like this : https://forum.opnsense.org/index.php?topic=51192.msg262139#msg262139 :)

I have a small script running that restarts IGMPproxy every night at 03:00 to prevent issues. Nobody is affected by it, and if someone happens to be watching TV at that time, it is only interrupted for a second or two.

Also, I personally think adding an extra device for such a small task is a bit overkill.
