209	* The default range is IPPORT_HIFIRSTAUTO through
210	* IPPORT_HILASTAUTO, although that is settable by sysctl.
211	*
212	* A user may set the IPPROTO_IP option IP_PORTRANGE to change this
213	* default assignment range.
214	*
215	* The value IP_PORTRANGE_DEFAULT causes the default behavior.
216	*
217	* The value IP_PORTRANGE_HIGH changes the range of candidate port numbers
218	* into the "high" range. These are reserved for client outbound connections
219	* which do not want to be filtered by any firewalls. Note that by default
220	* this is the same as IP_PORTRANGE_DEFAULT.
221	*
222	* The value IP_PORTRANGE_LOW changes the range to the "low" are
223	* that is (by convention) restricted to privileged processes. This
224	* convention is based on "vouchsafe" principles only. It is only secure
225	* if you trust the remote host to restrict these ports.
226	*
227	* The default range of ports and the high range can be changed by
228	* sysctl(3). (net.inet.ip.port{hi,low}{first,last}_auto)
229	*
230	* Changing those values has bad security implications if you are
231	* using a stateless firewall that is allowing packets outside of that
232	* range in order to allow transparent outgoing connections.
233	*
234	* Such a firewall configuration will generally depend on the use of these

236	* Administrator looking for you with a heavy object.
