Configuring Network
Address Translation
Network address translation (NAT) protects your net-
work by hiding its internal structure. It also provides
an effective way to conserve public IP addresses when
the number of addresses is limited.
At its most basic level, NAT translates the address of a
packet from one value to another. The “type” of NAT
performed refers to the method of translation:
Dynamic NAT
Also called IP masquerading or port address
translation. The Firebox either globally, or on a
service-by-service basis, applies its public IP
address to outgoing packets instead of using
the IP address of the session behind the
Firebox.
Static NAT
Also called port forwarding. Static NAT works
on a port-to-host basis. Incoming packets from
the external network destined for a specific
public address and port are remapped to an
address and port behind the firewall. You
must configure each service separately for
