Remote DLNA / UPnP Media Client / Controller

I have a MiniDLNA + Bubble UPnP Server running at home and I would like to access it remotely from my PC at work. I can check that the server is properly accessible though the Bubble UPnP App for Android, where I can enter the URL to my server. There is a wide range of UPnP client software for Linux, but non of them offers the possibility to enter an URL, which is quite hard to believe. During my search I checked all of them listed here on wikipedia , and all of them just search the local network for servers. Does anybody know a UPnP client / controller software which can deal with remote servers?
