I have an advanced setup running a PFSense firewall with an Unifi AC Pro and Unifi AC Mesh. I was able to transfer my old system, single SSID and single subnet, over to the new setup with multiple VLANs and multiple SSIDs. I’ve used PIMD for multicast routing across VLANs/subnets and Avahi for mDNS. Everything was working fine until I attempted to upgrade my rear Play 1s for One SLs in preparation for the Arc on the way.
Current configuration has a Playbar and a Sub both wired via Ethernet, independently, on the same VLAN. I also have a Play 5 and Play 1 connecting wireless. My iPhone connects via an SSID through the AC Pro on a separate VLAN. No problems playing to the any of the existing Sonos speakers. I have the SSID broadcast using both 2.4ghz and 5ghz.
My iOS Sonos app finds the new speakers and prompts me to press the link button on the backside of the One SL. After pressing the button, the iOS app doesn’t go further. It keeps requesting to try again.
Can I have someone look into a diagnostic to help? Or suggest I try something different? I have already restarted everything, including my special multicast and mDNS services on the PFSense.
