Hi, Refuse to use Sonos myself, but am helping (or trying to) out a friend who has a Sonos try to get things working wtih OpenBSD PF.
I've simplified their PF rulese to a simple swiss cheese (i.e. stateful NAT'd allow any out to any). Everything else they care to run on their network is running perfectly. Apart from their darn Sonos box. Sonos support are about as much use as a fart in spacesuit, so I'm hoping there's somebody on this list who has already fought and won the Sonos battle ? Thanks !
