183 * Local port number conventions:
184 *
185 * When a user does a bind(2) or connect(2) with a port number of zero,
186 * a non-conflicting local port address is chosen.
187 * The default range is IPPORT_RESERVED through
188 * IPPORT_USERRESERVED, although that is settable by sysctl.
189 *
190 * A user may set the IPPROTO_IP option IP_PORTRANGE to change this
191 * default assignment range.
192 *
193 * The value IP_PORTRANGE_DEFAULT causes the default behavior.
194 *
195 * The value IP_PORTRANGE_HIGH changes the range of candidate port numbers
196 * into the "high" range. These are reserved for client outbound connections
197 * which do not want to be filtered by any firewalls.
198 *
199 * The value IP_PORTRANGE_LOW changes the range to the "low" are
200 * that is (by convention) restricted to privileged processes. This
201 * convention is based on "vouchsafe" principles only. It is only secure
202 * if you trust the remote host to restrict these ports.
203 *
204 * The default range of ports and the high range can be changed by
205 * sysctl(3). (net.inet.ip.port{hi,low}{first,last}_auto)
206 *
207 * Changing those values has bad security implications if you are
208 * using a a stateless firewall that is allowing packets outside of that
209 * range in order to allow transparent outgoing connections.
210 *
211 * Such a firewall configuration will generally depend on the use of these
212 * default values. If you change them, you may find your Security
213 * Administrator looking for you with a heavy object.
214 *
215 * For a slightly more orthodox text view on this:
