Hello I am helping a friend set up Sonos in his vacation home. I've set up Sonos many times before (simple), but his particulars are stumping us. Here are the specifics: he has two homes next to each other, and they share an internet connection. Home 1 has the main internet pipe coming in, and then running through a router/firewall (Airport Extreme if it matters). Home 2 has an ethernet cable running from Home 1's Airport Extreme to its own router (Airport Express). Each of the wireless networks use different SSIDs etc, but obviously sharing the same network (and DHCP etc).
What we are trying to do is to create separate system for Home 2, so that if someone is renting it down there, they don't also see the other sonos products on Home 1's network. As it is now, when you join a mobile device to Sonos anywhere in home 1 or 2, you see all 6 sonos products. We'd like Home 2 to see only their zones and Home 1 to see only theirs.
I contend that the only way to do this is via some sort of subnet, or DMZ type of arrangement where Home 2 can't see the Sonos products on Home 1's network. Any thoughts on how to set this up?
