DLNA Server Not Found

view story

https://bbs.archlinux.org – I have a machine that does everything, it's my router, WirelessAP(s), NAS, etc. and I've set up a DLNA server on it, but it's not being seen by any DLNA compliant devices (DLNA apps on Android Tablet or a WDTV Live). I've tried both MiniDLNA and MediaTomb (not at the same time) and they both seem to run and work fine on the server, but no devices ever pick them up.Is there likely to be something I need to do to get this working in addition to just installing them? I thought it may be a port related issue so I installed and set up miniUPnPd as well, but that doesn't see (HowTos)
