Access Serviio from devices at another local network/interface

Hi,

I always worked with networks, ut never had a chance to play with it like now. Please I need some help.
Here is my setup:
I have a Mikrotik 750GR3 as a router of my local lan (very small, my apartment).
Eth 2-3 are from my local lan, the devices, IPAddress 192.168.0.1/24.
On Eth4 I have my services network (192.168.1.0/24), where, for now, I have a NAS (192.168.1.2) running Docker with some services installed, each one with it’s own IP address.

On of them is Serviio.

I have a TV with Kodi, where it access some shares on the NAS server and works perfectly. But I also have some other dumb TVs, which I had to buy a Chromecast for them to cast the movies, but with this setup, I do not have subtitles included. So, I installed Serviio to try to address this issue.
The problem, that I realised later, is that uPnP cannot be routed, works only on local network. So, none of the devices finds the Server. Even if I manually configure, it does not work.

I’m rusty on a lot of routing services and some of them are new to me.
I’d like to know if there’s some way (I don’t know, using routing, NAT, whatever…) to make my devices reach Serviio on 192.168.1.5 from 192.168.0.0 network… or I will have to change all my setup and put my NAS on the same network and change all Firewall rules.

Thanks a lot
