Can't connect to serviio on Synonlogy DS213

Dear all,

I have just installed serviio on my Synology NAS.
I have installed the console on my windows computer and add Media. It's ok I can see the media through the internal web site.
My NAS and my computer are under the same network.

Now I try to access it using VLC -> I can see all Windows Media but not the synology Serviio server.

Any Idea?

Thanks.

Update :
I have open DLNA port, Now I can read video, photo ... using Air Player on my IPad.

But only from the ipad. Using VLC, none of the computer are displaying the serviio server.

How about testing using XBMC - it's what I normally use for quickly testing something. Navigate to Videos then uPnP Servers I think.
