Is it possible to automatically alter the source port when using Nmap to
test a firewall?

Apparently it's not possible. I tryed this:

nmap -sS -P0 -g 2000-2010 127.0.0.1

but all packet comes from port 2000. Does anybody know a workaround? The only 
way I thinked about is to use a script to randomize source port on a dest 
port base, but I think it will be not efficient..
