network and nmap doubt

I was figuring out if I can discoverer how many computers are behind a
NAT. As far as I know a NAT works like state firewall by blocking some
types of TCP packages.
I assumed that NAT will (of course?) block SYN packages. So, I tried to
nmap -PA IP
nmap -sA IP
Both gave me just 1 Host Up. This is not true. My questions are:
1) Why it did not work ?
2) Is it possible to do it ? (I want to find out how, dont tell, just
say yes or no)
2a) Will it need scripts?
3) Where I can look out for Nmap's scripts ?
