new setup across vlans/subnets

[Neo]

Thanks for the replies
patience is a much needed commodity and it looks like I've had a bit of a boost.
God only knows what I've done but the tablet can see minimserver and play locally on bubbleupnp and they are in different vlans/subnets. Thats a massive win for me. I couldn't get the content of the library to be visible up till now (even though it could see the server itself).
I was really doubting everything. Like was there something I needed to do with minimserver? and not having a pc in that subnet means no minimwatch, was it my network config, a tablet setting, something in the nas, something with bubbleupnp server, did I need a upnp proxy. I didn't know which bits were working well or where to start.

I was starting to think about other options like webdav with cloudbeats or using music player daemon which would have probably been another learning curve to start

It must be playing across the subnets as all my port fowarding rules along with upnp / nat pmp are turned off. There's no internet access to my nas at all.
I've been fiddling with the settings on the tablet, Ive had apps that like all the network/location stuff enabled before so turned them on, and also in bubbleupnp there was a browsing mode - default, method 1 and method 2, currently on method 2. Not a clue if thats made a difference
The vlans that need to talk have intervlan enabled with some fairly loose firewall rules at the mo.
I disabled igmp snooping on the switches - they only allowed one vlan to be specified and I think if I want this function I'll need better switches that can perform this on multiple vlans.

I think I need to get a pi setup on the server lan just so I can use minimwatch - the minimserver config page loaded through the nas is kinda frustrating - it says its running but displays so little else in the way of detail or configs to change/try
Long road ahead to get it all working. Foobar on the office pc cant see anything, the pi running volumio hasnt been tried or any of the other stuff around the house, then there will be remote access, and maybe sort out the music itself too lol
