I'd like to enable clients on other VLANs (subnets) to be able to cast to a Chromecast on one particular subnet.
I've tried the Guest mode on the Chromecast, but guest users have had no luck in connecting for some reason.
I know that the Chromecast advertises its availability via Multicast but once a device is connected, communication is via unicast.
So two questions:
Unicast - I'm comfortable with configuring appropriate firewall rules, but need to know what protocols/ports to allow in which direction. I've tried to find online but no luck so far.
Multicast - I've never configured it before, but I know my router (Mikrotik RouterOS) supports it. I've read their wiki article on Multicast, but still a little unsure exactly how to configure.
I plan to add a DHCP reservation for the Chromecast on its existing subnet, 10.5.0.0/16 (10.5.2.x) and would like to allow clients on 10.6.1.0/24 and 10.9.2.0/24 to connect.
Any help appreciated. Thanks!
