! 82: * From FreeBSD:

! 84: * Local port number conventions:
! 85: *
! 86: * When a user does a bind(2) or connect(2) with a port number of zero,
! 87: * a non-conflicting local port address is chosen.
! 88: * The default range is IPPORT_RESERVED through
! 89: * IPPORT_USERRESERVED, although that is settable by sysctl.
! 90: *
! 91: * A user may set the IPPROTO_IP option IP_PORTRANGE to change this
! 92: * default assignment range.
! 93: *
! 94: * The value IP_PORTRANGE_DEFAULT causes the default behavior.
! 95: *
! 96: * The value IP_PORTRANGE_HIGH changes the range of candidate port numbers
! 97: * into the "high" range. These are reserved for client outbound connections
! 98: * which do not want to be filtered by any firewalls.
! 99: *
! 100: * The value IP_PORTRANGE_LOW changes the range to the "low" are
! 101: * that is (by convention) restricted to privileged processes. This
! 102: * convention is based on "vouchsafe" principles only. It is only secure
! 103: * if you trust the remote host to restrict these ports.
! 104: *
! 105: * The default range of ports and the high range can be changed by
! 106: * sysctl(3). (net.inet.ip.port{hi}{first,last})
! 107: *
! 108: * Changing those values has bad security implications if you are
! 109: * using a a stateless firewall that is allowing packets outside of that
! 110: * range in order to allow transparent outgoing connections.
! 111: *
! 112: * Such a firewall configuration will generally depend on the use of these
! 113: * default values. If you change them, you may find your Security
! 114: * Administrator looking for you with a heavy object.
