question on nmap utility

Hi all,
Is there any option that can be used with nmap utility that will enable it to scan the machines which are behind a firewall? or is there any other command/freeware which does that?
Any pointer will be helpful.
Thanks in advance.

Hello, Shourya.

Fyodor, the NMap author, is certainly a clever man, but I'm afraid he hasn't figured out how to code a psychic mode onto NMap.

With that said, you can logically deduce that there are machines behind a firewall by deducing information from open ports on the firewall itself, but enumerating and scanning the separate protected machines, I'm afraid, is impossible without a far more nefarious attack than NMap.
