To configure NAT, you need to: 

1. Enable Security; see the 

 section. 

2. Create at least two different security interface types based on existing LAN services; see 
the 

section

.

 

Once you have created more than one security interface, the NAT column in the Security 
Interfaces table tells you that you can enable NAT between the existing security interface and 
a network interface type. For example, if you create an external interface and an internal 
interface, your table will look like this: 

 

The NAT column for the external interface tells you that you can enable NAT to internal 
interfaces. If you also had a DMZ interface configured, this column would also include an 
Enable NAT to DMZ interfaces button.

Once you have enabled NAT between interfaces, you can: 

• Configure global addresses; see the 

Configuring NAT global addresses

• Configure reserved mapping; see the 

Configuring NAT reserved mapping 

section. 

Global address pools allow you to create a pool of outside network addresses that is visible 
outside your network. Before you can configure global addresses, you need to configure NAT. 
See 

Section 

If you want to set up a global address pool on your existing NAT enabled interfaces: 

1. From the NAT Security Interfaces table, click on the Advanced NAT Configuration 
hyperlink for the interface that you want to add a global pool to. The following page is
