Multicast Forwarding

[hachiko008]

1. I added push "route 224.0.0.0 240.0.0.0" to the OpenVPN server configuration file to allow multicast traffic. I also enabled IP forwarding by running sudo sysctl -w net.ipv4.ip_forward=1 and ensured this setting was persistent by adding net.ipv4.ip_forward=1 to /etc/sysctl.conf. Additionally, I allowed multicast traffic through the firewall with sudo ufw allow from 224.0.0.0/4.

2. I verified that both the device and the TV were on the same network/subnet. I added a route for the local network (push "route 192.168.0.0 255.255.255.0") to the OpenVPN server configuration to allow traffic between the VPN and the local network. I also updated the firewall rules to ensure the VPN could communicate with the local network.

3. modified the OpenVPN server configuration by adding client-to-client to allow VPN clients to communicate with each other. Finally, I restarted the OpenVPN service.

by doing so, nothing works just only for enabling to cast a device remotely while connected to VPN.

Thanks and well appreciated.
