Chromecast on two different subnets
We have a chromecast with an IP on our LAN Client.
This must be used by users of our company, as well as external service providers who are connected to our Wifi Guest VLAN.
We opened the UDP ports: 1-65535 UDP and 8008-8009 in TCP from our Chromecast to these two subnets and vice versa.
We have also authorized port 1900 on our subnet at 184.108.40.206.
We have also activated multicast on our 2 networks and activated the RP Candidate.
Despite this, we still cannot find the Chromecast when connected to our Guest Wifi.
I also specify that when I am on the internal wifi (client LAN), I can find the Chromecast on Google Chrome.
When I disconnect to connect to the Guest Wifi, I am able to stream normally to the chromecast.
The problem therefore seems to come from the discovery of this equipment in Guest Wifi.
Device discovery between networks does not seem to work.
Has anyone found a solution to make this work?
