I believe all devices will translate a privileged ports, but it won't translate to the same number on the other side. It will translate to an unprivileged port. Is it what you meant or really there are some devices that will not translate at all a privileged port?
What has been reported to us is that some boxes do not translate the src port if it's a privileged port. IN such scenarios, NTP implementations that always use src port=123, dst port=123 might be in trouble if there are multiple NTP clients behind the same NAT device.... Thanks!
