This new extension exposes the "enable_snat" flag of a router. The "enable_snat" flag can be updated using the external gateway API commands. However this is a router global configuration property that is stored directly on the router register. As described in the ``update-external-gateways-of-router`` API section [1]: "The enable_snat field does not have any effect for extra gateways except for the first external gateway in the list."
