NAT and Web Server Security
From: <spato99 () hotmail com>

We're about to put a public web server on DMZ sitting behind a Teir 1 
firewall and only allow http, ssl to it.  We intend to assign a public IP 
address to this server and no NAT'ing is done on the firewall for this 
address (NATing done for internal network on Teir 2 firewall).  

It has been suggested that without NATing, it is possible for a hacker to 
compromise this server and pretend to be our company...

1) While NAT address some security issues, doesn't this specific risk 
exist regardless of whether NAT is employed or not?

2) If NAT does help in this case, I'd appreciate comments as to how

3) Is there any good reading material on NAT security - specifically, 
what it can and can't protect against. The stuff I've read doesn't seem 
to talk about NAT in this context.


Thanks
