How do I configure the HSI clients and gateway to deal with firewalls?

Please see the section Restricted TCP Ports and Restricteded Mover Hosts for information on setting environment variables to define port ranges to enable connections from mover hosts to HSI/HTAR client machines, and for setting environment variables on the HSI Gateway host(s) to allow HSI firewall-mode transfers from client machines that are unable to open inbound port ranges.
