Configuring Static NAT or Static NAT with Port Translation
This section describes how to configure a static NAT rule using network object NAT. For more
information, see the “Static NAT” section on page 26-3.
Detailed Steps
Step 1 You can add NAT to a new or existing network object:
• To add a new network object, choose Configuration > Firewall > NAT Rules, then click Add >
Add Network Object NAT Rule.
Figure 27-15 Adding a Network Object NAT Rule
• To add NAT to an existing network object, choose Configuration > Firewall > Objects > Network
Objects/Groups, and then double-click a named network object. (Non-named network objects
cannot be configured for NAT. Named network object icons have dark blue accents, and non-named
network object icons have green accents and the word “IP”.)
For more information, see the “Configuring a Network Object” section on page 13-2.
The Add/Edit Network Object dialog box appears.
Step 2 For a new object, enter values for the following fields:
a. Name—The object name. Use characters a to z, A to Z, 0 to 9, a period, a dash, a comma, or an
underscore. The name must be 64 characters or less.
b. Type—Network, Host, or Range.
c. IP Address—An IPv4 address. IPv6 is not supported. If you select Range as the object type, the IP
Address field changes to allow you to enter a Start Address and an End address.
d. Netmask—Enter the subnet mask.
e. Description—(Optional) The description of the network object (up to 200 characters in length).
