[FW-1] Firewall DMZ



We are looking to create a dual firewall environment (external and
internal). In the middle will be the DMZ. Are DMZ IP addresses typically
hidden from the outside world? Aside from hiding this network from the
outside world, are there any additional advantages? I'm assuming that if I'm
hiding the DMZ addresses, I will need to NAT them. Are there any security
issues to NATing for inbound services (i.e. www)? Or is it recommended to
simpy route the DMZ IP addresses?
 
Thanks in advance
