Sonos Speakers not working on Meraki MR

[EdgeFarming]

Hi, 

We had a simple network using the WiFi from our ISP's modem. Sonos speakers were connected using this SSID and everything was working great. 

Sonos speakers have a functionality that sync and plays simultaneously in all the spearkers using multicast.

When the network was changed to a Meraki MR APs that functionality was lost. 

Does anybody know a fix to this?

Thanks

Hello,

Make sure that your SSID is set to bridge mode (External DHCP assigned), it does not have Layer 2 isolation and that the outbound rules are allowing local lan traffic on the Firewall & Traffic shapping menu.

Hi Purroy,

That's exactly how it's configured. Here the screenshots:

On top of @Purroy 's answer, the next most common issue I encounter is clients having "Deny Local LAN" enabled.  Make sure that is turned off.

Is your SSD's DHCP configuration in Bridge mode or NAT mode?

What about the SSID firewall configuration, is it allowing or denying access to the local LAN?

https://documentation.meraki.com/MR/Firewall_and_Traffic_Shaping/'Deny_Local_LAN'_settings_in_Cisco_...

Since the client isolation function of NAT mode prevents wireless devices on the SSID from communicating with other wireless devices, NAT mode is not recommended for use with wireless peer-to-peer devices like a wireless printer or Google Chromecast.

Hi Alemabrahao,

Everything is configured that way .Here the screenshots:

What about Bonjour?

Hi Alex. 

I have tried all this solutions before but it si still not working, we have four speakers but they never get sync, dont know the reason why. I have heard that sonos uses some kind of multicast but I ahve also checked and multicast is allowed. What else could I do?

Thanks
