Configuring the Application and Application Set (NSM Procedure)

You can define application protocols for the stateful firewall and Network Address Translation (NAT) services to use in match condition rules. An application protocol, or application layer gateway (ALG), defines application parameters using information from network Layer 3 and above. You can configure properties of an application and whether to include it in an application set using the application option. You can configure one or more applications to include in an application set using the application set option.

To configure an application set in NSM:

  1. In the NSM navigation tree, select Device Manager > Devices.
  2. Click the Device Tree tab, and then double-click the device to select it.
  3. Click the Configuration tab. In the configuration tree, expand Applications.
  4. Add or modify settings as specified in Table 1.
  5. Click one:
    • OK—Saves the changes.
    • Cancel—Cancels the modifications.

Note: Application and application set are configurable, only if the device is in the in-device policy mode.
