Configuring NAT translation

To configure NAT translation to discover NAT environments, map the address-space identifier for a NAT domain to the IP address of the associated NAT gateway device.

Prerequisites
Scoping discovery

About this task

After activating NAT, you must map the discovery scope zones to the NAT address spaces. You do this on the Scope tab.

If you select Enable Network Address Translation (NAT) Support in the NAT tab then you must configure at least one NAT gateway.

To configure NAT gateways:

Procedure

  1. Click the Discovery icon and select Network Discovery Configuration.
  2. From the Domain list, select the required domain.
  3. Click NAT.
  4. Add a new NAT gateway, or edit an existing gateway:
    • To add a new NAT gateway, click New New button.
    • To edit an existing NAT gateway, click the IP address in the required row.
    The NAT Gateway page is displayed.
  5. Complete the fields as follows and click OK:
    IP Address
    Type the public IP address of the NAT gateway device.
    Address Space
    Type the address space identifier that you want to use for the associated NAT domain.
  6. Click Save Save button.
  7. To activate NAT translation for the discovery, select Enable Network Address Translation (NAT) Support. Click Save and then map the discovery scope zones to the NAT address spaces:
    1. Click Scope.
    2. Click a scope zone to edit it.
      The Scope Properties page is displayed.
    3. In the Address Space field, enter the NAT address space and click OK.
      The Address Space field appears on the Scope Properties only after the Enable Network Address Translation (NAT) Support has been selected.
    4. Repeat the previous two steps for all the required scope zones.
    5. Click Save Save button.
    NAT Address Spaces Dynamic Distinct view is created automatically if Enable Network Address Translation (NAT) Support is turned on. Once discovery is complete, use the Network Views to visualize the NAT Address Spaces network view.
