DELL SonicWALL - get AirPlay and DLNA working between bridged LAN and WLAN


  • DELL SonicWALL NSA 220 wireless-N
  • LAN and WLAN interfaces Bridged (on the same subnet)


  • Streaming protocols that rely on multicast (such as Apple Bonjour/AirPlay and DLNA/UPNP) don't work between devices that span LAN and WLAN zones.
  • If all devices are either on Wireless or Wired part of the network, everything works fine.

On residential routers you would normally expect such streaming protocols to work between LAN and WLAN with no additional configuration, but because SonicWALL is a business grade firewall, it needs some additional configuration to allow multicast traffic between wired and wireless clients.
