Setting Interface Options for IPS Engines

Interface options allow you to select which interfaces are used for which types of system

communications.

 To set the Interface Options

1. Click Options. The Interface Options dialog opens.

2. Select the Primary Control IP address for communications with the Management Server.

3. (Optional) Select a Backup Control IP address for Management Server contact (used if the

Primary fails).

4. (IPS Cluster only) Select the Primary Heartbeat Interface for communications between the

nodes of the cluster. This must not be a VLAN Interface.

5. (IPS Cluster only, recommended) Select a second Physical Interface as the Backup

Heartbeat Interface.

6. (Single IPS only) Select Node-initiated contact to Management Server if the IPS engine is

behind a device that applies dynamic NAT to the inbound management connections or

blocks them.

7. Select the Default IP Address for outgoing traffic.

8. Click OK.

Caution – Heartbeat traffic is time-critical. A dedicated network (without other traffic) is

strongly recommended for security and reliability of heartbeat communication.
