problems with Airplayer 3.0.1

I have installed Aiplayer 0.3.1 on my duo running BH 2.0.1 but my iphone does not see E2 Airplayer when I push the airplay icon. I get a message that Airplayer is running on the box but it doesn't appear in iphone or itunes.

I've got the interface set to eth0 as I'm using a wired connection.

Any help/suggestions welcome
