Local Network over OpenVPN

[Jobine]

Hi,

When I connect with OpenVPN on my computer, I have full access to my NAS via local network, I see my UPNP server in the list.

But when I connect to my VPN with my iOS device (iPhone or iPad), I don't see my UPNP server.

Somebody know why ?

Thank's

anyone know what ports is required for the discovery of UPNP server (Twonky) and on which it runs.
