IPFW closing range of ports

[Matthew Walker]

You could starve it by using a pipe, allocate 16 kbit/sec. Then 
technically you aren't blocking it.

ipfw add 1000 pipe 10 tcp  from any to any 14500-65535 out
ipfw pipe 10 config bw 16k queue 100 mask dst-ip 0xff000000

Otherwise, you can block the ports:
ipfw add 1000 deny tcp from any to any 14500-65535 out

Depends on how much of a BOFH mood your are in that day.
