I've both a Philips Streamium Upnp player and a Samsung smart TV. Twonky served via Zyxel nas326 is readily available to these devices when connecting over WiFi. However neither player can see the Twonky server when connecting with a wired Ethernet cable. WAN internet connection is immediately recognized over Ethernet on both devices.
What must be done to allow Twonky over an Ethernet connection?
