228
 * Local port number conventions:
229
 *
230
 * When a user does a bind(2) or connect(2) with a port number of zero,
231
 * a non-conflicting local port address is chosen.
232
 * The default range is IPPORT_HIFIRSTAUTO through
233
 * IPPORT_HILASTAUTO, although that is settable by sysctl.
234
 *
235
 * A user may set the IPPROTO_IP option IP_PORTRANGE to change this
236
 * default assignment range.
237
 *
238
 * The value IP_PORTRANGE_DEFAULT causes the default behavior.
239
 *
240
 * The value IP_PORTRANGE_HIGH changes the range of candidate port numbers
241
 * into the "high" range.  These are reserved for client outbound connections
242
 * which do not want to be filtered by any firewalls.  Note that by default
243
 * this is the same as IP_PORTRANGE_DEFAULT.
244
 *
245
 * The value IP_PORTRANGE_LOW changes the range to the "low" are
246
 * that is (by convention) restricted to privileged processes.  This
247
 * convention is based on "vouchsafe" principles only.  It is only secure
248
 * if you trust the remote host to restrict these ports.
249
 *
250
 * The default range of ports and the high range can be changed by
251
 * sysctl(3).  (net.inet.ip.port{hi,low}{first,last}_auto)
252
 *
253
 * Changing those values has bad security implications if you are
254
 * using a a stateless firewall that is allowing packets outside of that
255
 * range in order to allow transparent outgoing connections.
256
 *
257
 * Such a firewall configuration will generally depend on the use of these
258
 * default values.  If you change them, you may find your Security
259
 * Administrator looking for you with a heavy object.
260
 *
261
 * For a slightly more orthodox text view on this:
262
 *
263
 *            ftp://ftp.isi.edu/in-notes/iana/assignments/port-numbers
264
 *
265
 *    port numbers are divided into three ranges:
266
 *
267
 *                0 -  1023 Well Known Ports
268
 *             1024 - 49151 Registered Ports
269
 *            49152 - 65535 Dynamic and/or Private Ports
