Hey everyone,

I'm currently using Unifi to handle my home network, I have a main network for personal devices such as a NAS, PC, phones, tablets etc, an IoT network which require an internet connection and then I've made a network for devices that don't require an internet connection. By default the IoT network and no internet access network can't open communication with any other network but their own except to speak to my home assistant server, the main network however has full access and I'm finding that when my TV and Fire Cube are on the IoT network I can no longer cast to them even when I disable all the firewalls for my IoT and other network.

Has anyone else experienced this / found a solution? when I try searching online I get a lot of stuff about chromecasts but not direct casting from a PC.

It is normal for casting to not go across VLan - you need to turn stuff on to do it = have a look at this

Hi, Chromecasting and Airplay use mDNS to discover devices, if you want to route mDNS requests across subnets you will need an Avahi router on the network to achieve this. Some wireless products (Aerohive and Ruckus are two I know of) have Avahi built in to allow this.

I've tried turning multicast DNS on in the advanced settings, sadly it doesn't work. The cast option doesn't come up when bringing up a YouTube video on the PC.

Hi UniFi does not support mDNS discovery, as mentioned you will need to deploy a seperate Avahi service on the network.

I can see a few tutorials with pfsense but I can't see anything outside of this, do you have any recommendations on the best way to set this up with a Unifi network

Hi, Avahi -deamon is built into most Linux distros, so you will need a linux instance on your network and all the vlans available to it. I presume there is a windows service available, but I have no interest in that so never looked.
