! 266: * When a user does a bind(2) or connect(2) with a port number of zero,

! 268: * The default range is IPPORT_HIFIRSTAUTO through
! 269: * IPPORT_HILASTAUTO, although that is settable by sysctl.
! 270: *
! 271: * A user may set the IPPROTO_IP option IP_PORTRANGE to change this
! 272: * default assignment range.
! 273: *
! 274: * The value IP_PORTRANGE_DEFAULT causes the default behavior.
! 275: *
! 276: * The value IP_PORTRANGE_HIGH changes the range of candidate port numbers
! 277: * into the "high" range. These are reserved for client outbound connections
! 278: * which do not want to be filtered by any firewalls.
! 279: *
! 280: * The value IP_PORTRANGE_LOW changes the range to the "low" are
! 281: * that is (by convention) restricted to privileged processes. This
! 282: * convention is based on "vouchsafe" principles only. It is only secure
! 283: * if you trust the remote host to restrict these ports.
! 284: *
! 285: * The default range of ports and the high range can be changed by
! 286: * sysctl(3). (net.inet.ip.port{hi,low}{first,last}_auto)
! 287: *
! 288: * Changing those values has bad security implications if you are
! 289: * using a stateless firewall that is allowing packets outside of that
! 290: * range in order to allow transparent outgoing connections.
! 291: *
! 292: * Such a firewall configuration will generally depend on the use of these
! 293: * default values. If you change them, you may find your Security
