Add multicast route

You can configure Sophos Firewall to forward multicast traffic. You need to configure multicast routes when traffic from a single source is routed to multiple receivers, for example video conferencing.

In this scenario, a client in the LAN zone behind Sophos Firewall is part of a multicast group. You assign the client an IP address of 227.0.0.100. It receives multicast traffic from an external media streaming server with the IP address, 202.247.250.200. You configure Sophos Firewall to forward multicast traffic from the external media server to the client listening for the multicast traffic, as shown in the following diagram:

To add a multicast route, do as follows:

1. Go to Routing > Static routes.
2. Under Multicast forwarding setting, select Enable multicast forwarding, click Apply, and click OK.
3. Under Manage multicast route, click Add.

4. Enter the multicast route details.
