Drop-In Mode

In a drop-in configuration, your XTM device is configured with the same IP address on all interfaces. The drop-in configuration mode distributes the network’s logical address range across all available network interfaces. You can put your XTM device between the router and the LAN and not have to change the configuration of any local computers. This configuration is known as drop-in mode because your XTM device is dropped in to a previously configured network.

In drop-in mode:

The properties of a drop-in configuration are:

It is sometimes necessary to clear the ARP cache of each computer protected by the XTM device, but this is not common.

If you move an IP address from a computer located behind one interface to a computer located behind a different interface, it can take several minutes before network traffic is sent to the new location. Your XTM device must update its internal routing table before this traffic can pass. Traffic types that are affected include logging, SNMP, and XTM device management connections.

You can configure your network interfaces with drop-in mode when you run the Quick Setup Wizard. If you have already created a network configuration, you can use Policy Manager to switch to drop-in mode. For more information, see Run the Web Setup Wizard.

Use Drop-In Mode for Network Interface Configuration

  1. Select Network > Interfaces.
    The Network Interfaces dialog box appears.
  2. From the Configure Interfaces in drop-down list, select Drop-In Mode.
  3. In the IP Address text box, type the IP address you want to use as the primary address for all interfaces on your XTM device.
  4. In the Gateway text box, type the IP address of the gateway. This IP address is automatically added to the Related Hosts list.
