Destination NAT

Destination NAT is performed on incoming packets, when the firewall translates a public destination address to a private address. Destination NAT does not use address pools or ranges. It is a 1-to-1, static translation with the option to perform port forwarding or port translation.
Static IP —Allows the 1-to-1, static translation of a destination IP address and optionally the port number.
One common use of destination NAT is to configure several NAT rules that map a single public destination address to several private destination host addresses assigned to servers or services. In this case, the destination port numbers are used to identify the destination hosts. For example:
Port Forwarding —Can translate a public destination address and port number to a private destination address, but keeps the same port number.
Port Translation —Can translate a public destination address and port number to a private destination address and a different port number, thus keeping the real port number private. It is configured by entering a Translated Port on the Translated Packet tab in the NAT policy rule. See the Destination NAT with Port Translation Example.
