8.1 through 9.1RC will use net.inet.ip.portrange.hifirst (49152) to .hilast (65535) for ephemeral ports as far as I'm aware. net.inet.ip.portrange.first to .last are just a reference to available port numbers as per RFC6056
Correct me if I'm wrong but netinet/in_pcb.c:490 indicates this is the case. -Colin On 12 Nov 2012, at 17:57, Dustin Wenz wrote: > 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.
