Ya, clients typically do use random ports, I am only speaking from a
server standpoint (Enterprises don't typically static nat a client).

Well for TCP, the NATs don't muck with ports at all. The clients I have
for
HTTP, SMTP, FTP, also use source ports different than the destination
ports
so that the clients don't have to open a port under 1024 which would
require
them to be running as root.
