I'm using OpenDDS and have a port question. How does the publisher know what port to send to, or what port the subscriber is accepting from?

Below is a config file for my publisher, and I was expecting data to be sent to port 52000 on the remote machine, but I run a netstat and don't see 52000 even listining when I run the subscriber.

I'm trying to send my data to a proxy server that will relay this to the remote host, but not sure how to configure this type of port control yet.

# This "common" section configures the data in Service_Participant.

# Debug Level

# IOR of DCPSInfoRepo process.

# Configuration for a specific TransportImpl object. The section name
# has the "transport_impl_" as prefix and appeneds with the transport id
# which is an integer. The integer must match the transport_id integer
# used in the code.

# The local endpoint with host:port format (e.g. localhost:4444).
# Without specifying local_address or without specifying port number in
# local_address(e.g. localhost:-), the OS will pick a random port.
# This would avoid the impact of using a port currently used by other
# applications.
