static NAT vs hide behind an IP

Can someone explain?

I understand when a host "hide behind the GWY and hide behind the IP", but not the difference between the following config. Are they not the same?

Re: static NAT vs hide behind an IP

Hide is used to "overload" single IP for outbound traffic.

Static is used for inbound connections to the servers you are hosting.

If you have a number of public IPs and you are hosting a server behind the gateway that the external clients must connect to, you use Static NAT.

I.e.: You have 222.222.222.0/24 public range, your gateway is 222.222.222.1, your internal network is 10.0.0.0/24 and your DMZ is 192.168.255.0/24.

You configure Web server in DMZ with IP of 192.168.255.2 and Statically NAT it to 222.222.222.2.

Your internal network 10.0.0.0/24 is Hiding behind gateway's IP of 222.222.222.1.

Inbound traffic to your web server will be translated to its private IP address 192.168.255.2.
