Configuring Flash Media Server to support IPv6 and IPv4

By default, Flash Media Server is configured to support IPv4 only, even if the OS is configured for IPv6. However, one Flash Media Server can support both IPv6 and IPv4 addressing. Edit a config parameter in the Server.xml file to add support for IPv6. The Server.xml file is located in the fms/conf folder (Linux) or Flash Media Server 3.5\conf folder (Windows).

<NetworkingIPv6 enable="true" />

When IPv6 is enabled, if an IPv4 client connects, it has an IPv4 connection. If an IPv6 client connects, it has an IPv6 connection. The server listens for IPv4 and IPv6 addresses. You can see these connections in the server logs. To see an example in an edge log, see Configure IPv6 in the Flash Media Server docs.

Remember, you also have to configure the OS networking stack to support IPv6 and activate IPv6 on the nic– see the OS docs for instructions. Also, to use a numeric IPv6 address in a client-side script, server-side script, or in the server configuration files, enclose the address in brackets:


For link-local addresses, specify the interface zone index:
