I have a VPN server in my network and I use it to connect Yatse on my phone to the Kodi server when I am not at home so I can stream media content (music mainly, but also a video from time to time). Some times I forget to wake Kodi up when I leave home, and right now it is not possible to do so through VPN with Yatse; my guess is that the broadcast is only done in the WAN/4G connection of the phone but not in the VPN; however, using Fing I am able to specify not only the MAC but also the IP of computer I want to wake up and then the packet reaches its destination through the VPN connection.
Right now it is not a big deal because, as I say, I can use Fing to wake Kodi up in such scenario, and it is not like I am going to uninstall Fing from my phone anyway, but it would be great if this functionality were also available in Yatse to make it perfect something that is already excellent
