According to:
ftp://ftp.isi.edu/in-notes/iana/assignments/port-numbers
port numbers are divided into three ranges:
0 - 1023 Well Known Ports
1024 - 49151 Registered Ports
49152 - 65535 Dynamic and/or Private Ports
This patch changes the "local port range" from 40000-44999
to the range shown above (plus fix the comment in in_pcb.c).
WARNING: This may have an impact on firewall configurations!
