Title: IGMP Proxy broken after upgrade to 25.7.10
Post by: Shoog on December 22, 2025, 11:03:47 PM
Hi,
I upgraded last night to the latest version 25.7.10
It errored out in the middle of the first upgrade and told me to repeat the process which seemed to complete successfully.
However ever since I have the error


2025-12-22T21:52:35
Warning
igmpproxy
MRT_DEL_MFC; Errno(49): Can't assign requested address

As everyone will be aware IGMP Proxy is essential for correct functioning of multicast sat. signals on the local network and IPTV, and since the upgrade these are now broken on my local network.

Is anyone else experiencing this after the latest upgrade ?
Seems when this has happened previously its not a straightforward fix and can take considerable time for a solution to be rolled out. Really bad timing two days before Xmas.

I believe I have a temporary workaround by directing all my network traffic through a dumb switch. Should hopefully get me through Xmas. A bit early to tell if this is a robust solution.
The underlying issue remains though.

Have a look at the "snapshots" feature (a.k.a ZFS boot environments) for future upgrades:

It doesn't fix broken plugins but it sure can spare a ruined holiday.

Also use IGMP Proxy here. No issues with the upgrade and IGMP is working as it should. I have a standard configuration for KPN (NLD ISP) IPTV.

Upstream is configured for the IPTV platform
213.75.0.0/16, 217.166.0.0/16, 195.121.0.0/1

Downstream has my IPTV LAN VLAN 192.168.40.0/24

My IGMP Proxy is definitely throwing errors and the behaviour of my network is entirely in keeping with what you would expect from IGMP failure.
I wonder if the error i saw when performing the upgrade is the cause.
Is it possible to rerun the upgrade over the top of the existing upgrade (ie 25.10.7 over 25.10.7) to eliminate this as the possible root cause.
