That's correct.

Your "in" and "out" seem reversed.
Let computer A send data-products to computer B, then any firewall
between A and B must allow packets to go from any port on B to port 388
on A. The firewalls must also allow packets to go from port 388 on A to
the port on B that was used to establish the TCP connection.
OK?
