I'm trying to determine why the default ephemeral port range appears to be 10000 through 65535 in at least 8.1 through 9.1RC. Documentation regarding the lower bound on the range seems inconsistent. The FreeBSD website (http://wiki.freebsd.org/SystemTuning) suggests that net.inet.ip.portrange.first defaults to 49152, which I don't believe is accurate. The IANA recommends the range be 49152 through 65535 (http://tools.ietf.org/html/rfc6056). Is there any particular reason why net.inet.ip.portrange.first defaults to 10000? - .Dustin
