OPNsense and Devices running mDNS

[ricksense]

Hi,
I was watching this video:

and I also read this OPNsense wiki:

https://docs.opnsense.org/manual/how-tos/multicast-dns.html?utm_source=pocket_reader


I need to figure out how it works exactly. So, sorry if my question may sound stupid to the most.

Assuming that I have a smart tv or something running on subnet 172.16.69.0/24 which uses mDNS and needs to communicate with a server on LAN 192.168.3.0/24 in order to get media contents, would the setup shown in the video be the same on OPNsense after installing Multicast DNS Proxy?

Thanks
