What is needed for DLNA visibility on the network?

Question

WiFi

There is a home network configured as follows, indicated in the ball
. In the internal network 192.168.0.0, the server with minidlna seems fine. I'm trying to make it visible to WiFi devices that connect directly to the modem. In the router from 192.168.178.20 I made NAT forwarding to
tcp:8200, udp:1900, udp:58176.
In the browser of the wif-device, port 192.168.178.20:8200 data is normally transmitted, but all sorts of players do not want to see it.
In general, how to overcome such blindness? In the player, you need to select streaming and specify the connection string. Just a network address is not enough. When specifying port 8200, it also does not open. What connection string should be for a connection?

Transfer all devices to the same subnet - 192.168.178.0 or 192.168.0.0.
Remove the wire from the modem from the WAN hole of the router and stick it into any of the LAN holes.
Leave DHCP alone - either on the modem or on the router. Turn off the second.
