This setup is in a corporate environment. The Sonos lives on it's own subnet (VLAN 10), and guests connect to another (VLAN 20).
I have a Bonjour gateway configured so that devices on VLAN 20 can see the Sonos advertising AirPlay on VLAN 10. Also, for the purposes of troubleshooting, I've allowed all traffic between both VLANs. This is working as expected, clients can connect and begin streaming.
The issue I'm having is that I'm experiencing random 1-2 second dropouts, and after ~15 minutes the connection will completely drop.
A packet capture shows everything humming along just fine until the Sonos sends a TCP reset and the client disconnects.
The issue does not occur when both devices are on the same VLAN. This issue happens with multiple clients and all of my Sonos AMPs.
This happens to both wired and wireless clients. The AMPs are wired. The basics of the network are: Meraki WAPs and Switches, SonicWALL routing all traffic. Bonjour gateway setup on Meraki.
