-- i have a Sonos Playbase
-- i have a firewall server box with 3 network cards: WAN, LAN, IOT
-- i have a LAN subnet which is my desktop, laptop, and file server box. (macOS)
-- i also have an IOT subnet which is stuff like Alexa, home automation, PS4, TV, and my Sonos.
-- IOT cannot even see the LAN computers
-- however, LAN can connect and ping/ssh/etc into any of the IOT as long as the connection originates on the LAN side.
the basic issue is that i cannot get Sonos app, or Spotify app, (or the iOS Sonos app) on the LAN side to find my Playbase on IOT subnet.
the Playbase has a static IP and i can ping it just fine from the LAN side.
and my Echo can see the Playbase on the IOT side fine.
(and i can play from Echo from Spotify on the Playbase)
how do i get the Sonos app to connect to my Playbase on a different subnet?
is there a port forward i can setup?
can i emulate a Sonos device (in linux) on my LAN that forwards to IOT?
