Raspbian, client 2.10.3 network lock prevents UPnP media server discovery

[atreceu 0]

On my Raspberry Pi 2 model b, as soon as I enable AirVPN's network lock feature, my shared media servers on Raspbian are no longer discovered by other devices. If I, say, make a playlist from the Raspberry media server on another device, and then activate the network lock, I can still access and play the content that's in the playlist, but can no longer browse or see the media library. "Allow lan/private" and "Allow ping" are checked in the settings. I can access SMB shares and connect the Raspbian with ssh with the network lock on, no problem.

Is there some way to manually edit iptables to allow the exchange of UPnP discovery messages?

I also have the same problem, any suggestion would be welcome.
