Using Static NAT

Static NAT (or one-to-one NAT) allows the mapping of Internet IP addresses or address ranges
to hosts inside the internal network.
This is useful if you want a computer in your private network to have its own Internet IP address.
For example, if you have both a mail server and a web server in your network, you can map each
one to a separate Internet IP address.
Static NAT rules do not imply any security rules. To allow incoming traffic to a host for which
you have defined Static NAT, you must create an Allow rule. When specifying firewall rules for
such hosts, use the host's internal IP address, and not the Internet IP address to which the internal
IP address is mapped.
Note
Static NAT and Hide NAT can be used together
