Host won't know and host firewall is not an issue, so any port will be 
fine with clients initiating connection.

I am not sure if we have an external that can send and receive data and 
whose connection is initiated by a client to a host. In other words:

1) client connects to a host (TCP or UDP, or something else that is 
ideally already a part of an existing external)

2) client can send data to host AND host can send data back to client

Best,

I ask to see if there is an existing graceful way of user-initiated bidirectional connectivity that helps bypass firewalls and other less user-friendly circumstances? Otherwise, this may require a new external...
