Can Volumio integrate a source from another subnet?

I have 2 apartments that are connected via 2 Fritzboxes. Unfortunately, in my case I have to assign 2 subnets

  1. 192.168.178.0 and

  2. 192.168.200.0

Volumino is in #2, my Melco network storage is in #1. I can play music from my Melco with all other systems, regardless of whether it is in #1 or #2.

Can I assign a source in another subnet?

I enabled SSH on my Volumio an can ping my Melco:

volumio@volumio:~$ ping 192.168.178.32

I have MinimServer on my Melco - why isn’t Volumio able to use that device?

I am listening all my music here in network #2 with Foobar on iOS.
