I have two homes connected with a site-to-site VPN. Each home has its own Sonos System.
Ideally when at Home A, my app controller should only “see” the Sonos gear from Home A. (And same goes for home B). This is to prevent accidentally playing music in the other home.
Most of the time things work the way I want them to.
But when I travel from one home to the other, it takes a while for the controller to “see” it is at the new location. E.G. when at Home A, the controllers “see” the Sonos devices from Home B. (and vice versa - while at Home B, the controllers see Home A’s Sonos devices)
Some additional information about the environment:
The homes are on two different subnets - Home A uses 192.168.0.XXX and Home B uses 192.168.1.XXX.
In my firewall / vpn configuration, I have blocked each Sonos device’s site-to-site IP addresses.
Restarting the controller (phones) does not fix the issue.
The behavior occurs in both Android and iOS devices.
Is there a list of ports I should lock down site-to-site to prevent my controller from communicating with the wrong Sonos system?
Thanks for your help.
