IGMPProxy and Sonos

Hi @all,

i want to use my Sonos controller (noson) from green and all my sonos speaker are in blue.
So i used this source:

This is my igmpproxy config:

phyint blue0 downstream ratelimit 0 threshold 1
phyint green0 upstream ratelimit 0 threshold 1

I see a lot if traffic in debug log of igmpproxy but only from blue devices.
So i think that the proxy will work.

I created this FW rules:

green → port 1900 and 1901
blue → port 1900 and 1901

blue → IGMP (
IGMP → blue

green → IGMP
IGMP → green

green → group sonos speaker port 1400, 1443 and 4444 all TCP
group sonos speaker → green port 3500, 3400:3401 all TCP

The Controller isn’t discover my Sonos speaker.
But i can see that the Controller is trying.

Did anyone get that working?

Thanks Frank

From the console, you could use tail on the kernel logs with the -f switch (ctrl-c to stop) and while the controller looks for the speakers see if you get some hints.

tail -f /var/log/messages
