The rendering of the REDIRECT action is specific to the configured
traffic plumber, which in turn would depend on the underlying network

I suspect you are using the default configuration, in which case a
traffic stitching plumber is used, and for the choice of Neutron FWaaS

Creating the service instances in the appropriate context is enough to
get the traffic to flow through the services configured in the chain.
