Managing Network Address Translation Settings

Network address translation entries can be used to set up a one-to-one correspondence between an external
address on the firewall and the RFC1918 address of a host behind the firewall. This is often set up to allow
connections to an internal server from outside the network.
NOTE
Destination Network Address Translation (DNAT) can be setup by configuring the destination zone in a
rule. For more information on rules, refer to
The following sections describe how to configure and manage network address translation settings for a firewall:
• Section 5.17.12.1, "Viewing a List of NAT Settings"
