Many clients when creating connections use an ephemeral port for the local port. If a message
is routed to that host, the port specified in the host's address will be different than the
remote port of any existing connection with the host. Many MRF protocol implementation have an
'ignore_clientside_port' attribute in their router profile. Setting attribute to 'true' instructs
MRF that any connection created by the host (client side) that matches the transport, remote IP
and rtdom_id may be used.
