Selecting Interfaces when GWR Resides Inside an NFX Box

The physical interfaces of an NFX box are mapped to the virtual interfaces of the Gateway Router (GWR) (vSRX) as given in Table 1. These are the default mappings provided by CSO. You may change these interface mappings based on your requirements, see Configuring a Single Site.

When you create a new NAT rule and an NFX physical interface is intended as the source endpoint, select the respective mapped GWR interface.

Creating Addresses from Source Field

You can use one of the following ways to create a new address from the Source field and use the newly created address as a source endpoint:

• Type the address directly in the Source field. If the address is valid, it is created immediately and added as a source endpoint.

• Create an address from the Source field, using the following steps:

  1. In the Source field, type addr. The Add new address link appears at the bottom of the list of addresses.
  2. Click Add new address to create a new address.

     The Create Addresses page appears.

  3. Configure the new address. See Creating Addresses or Address Groups.
  4. Click Save to save the new address.

     The new address is created, and will be listed as an option for the source. Select the new address to add it to the source.
