-In the configuration settings above, the port 9617 was chosen out of a hat; there is no reason it cannot be any port on the system.  9618 is often chosen; it is the well-known port of the HTCondor collector.  In our setup, we are not assuming that there is a collector in the 192.168.0.0/24 network that will be contacted from outside 192.168.0.0/24, so 9618 is also a valid port number; but you may well want to avoid 9618 if you have an internal collector.  Note that the =TCP_FORWARDING_HOST= must match the external address of the collector.
