Discover Windows machines in other network

I have my Windows computer in network 192.168.1.0/24 plugged into one interface of my router.
I have another port on the router as network 192.168.168.0/24 where my nas is plugged in.
Now Windows doesn't discover my NAS automatically, of course. Anyone know what would be the most elegant way to solve this problem? The DLNA clients also don't discover my NAS properly, since they are all in the 192.168.1.0/24 network.

Should I just give my Windows PC a second virtual IP in the 192.168.168.0/24 network and bridge the two interfaces on my router?

Any help greatly appreciated!

I believe that DLNA uses Multicast to advertise itself, so depending on the router you are using you may be able to configure something like IGMP to enable multicast routing.

thanks a lot for the pointer i will try that! i didnt know where to start but this is very helpful thanks!
