Setting Interface Options for Layer 2 Firewall 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. (Layer 2 Firewall Cluster only) Select the Primary Heartbeat Interface for communications

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

5. (Layer 2 Firewall Cluster only, recommended) Select a second Physical Interface as the

Backup Heartbeat interface.

6. (Single Layer 2 Firewall only) Select Node-initiated contact to Management Server if the

Layer 2 Firewall engine is behind a device that applies dynamic NAT to the inbound

management connections or blocks them.

7. (Optional) 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.
