Example: Creating a source NAT rule
This example defines a unique NAT address to use for outbound packets originating from the DMZ network.
This example assumes there are address definitions defined for Port B named “Internet (Port B)”, an
address defined for the DMZ named “DMZ-network”, and an address defined named “Internet-Alias” to
translate the IP address. For information on defining addresses, see
Adding an IP address or range .
