Dear peplink engineering team. The last 6 deployments we’ve done for residential customers all had SONOS speakers and its been really really boring to redesign what should have been a deliver-to-site-and-it-works solution that we provide to work with the SONOS products.
In our case we need to be able to support SONOS speakers on the WAN and on a different VLAN (typically one or the other not both) and their control and management by the SONOS app on the client’s handheld devices.
I note that there is a SSDP/uPNP multicast relay utility on github here GitHub - alsmith/multicast-relay: Relay multicast and broadcast packets between interfaces. that looks like it should work.
There is also a post here https://en.community.sonos.com/troubleshooting-228999/multiple-subnets-vlans-and-sonos-workable-clavister-solution-30950 that describes the ports needed as well as the selective Multicast relay required for SONOS discovery.
Please can this be investigated to see if Peplink device might support SONOS forwarding like this in the near future…
Thanks,
