Control Network Traffic > Traffic Management & QoS > Set Connection Rate Limits

Set Connection Rate Limits

To improve network security, you can create a limit on a policy so that it only filters a specified number of connections per second. If additional connections are attempted, the traffic is denied and a log message is generated.

You can also configure the policy to generate an alarm when the connection rate limit is exceeded. You can configure the alarm to make the Firebox send an event notification to the SNMP management system, or to send a notification as an email message or a pop-up window on the management computer.

To configure connection rate limits, from Fireware Web UI:

  1. Select Firewall > Firewall Policies or Firewall > Mobile VPN IPSec Policies.
    The Policies page appears.
  2. In the Policy Name column, click the name of the policy to edit.
  3. Select the Advanced tab.
  4. Select the Specify Connection Rate check box.
  5. In the adjacent text box, type or select the maximum number of connections that this policy can process each second.
