Hi
I have two USG210 firewalls connected to each other via a site-to-site VPN connection over the internet.
The connection is active and I can access it on all devices, but I was trying to transmit a multimedia stream via chromecast, but I can't reach it.
I can only reach it from the local network.
How could I go about solving the problem?
A thousand thanks
Greetings

    Hello @Manuel13

    The Chromecast mirror function could only work in the same IP subnet.

    If you would like to transmit "Bonjour" "SSDP" multicast protocol from another subnet, the device must support multicast cross subnet routing. However, currently Zywall only supports IGMP proxy.


    Thanks!

    James.

    Do you mean which Zyxel product is compatible with "Bonjour" "SSDP" multicast?
    Currently, Zyxel Firewalls support IGMP Proxy over VPN tunnel.
    Bonjour service only works when client and server are in the same IP broadcast subnet. This kind of multicast doesn’t support in current VPN scenario on Zyxel Firewalls.
    Thank you.

    James.
