By default, the Active Flow Timeout value on the Firebox is 30 minutes. If the Active Flow Timeout value is lower on the collector, the collector might stop listening while the Firebox is sending data. We recommend that you specify an Active Flow Timeout value that is lower than the Active Flow Timeout value on the collector.

In the Active Flow Timeout text box, type a number between 1 and 60 minutes.

The Firebox must be able to communicate with the collector at the specified IP address and port with the UDP protocol.

In the Port text box, type the port configured on the collector.

In the Collector Address text box, type the IPv4 or IPv6 address of the collector.

In Fireware v12.7.1 or higher, post-NAT addresses appear in flow records if you select V9. To monitor IPv6 traffic, you must use V9.

For the protocol version, select V5 or V9.

To configure NetFlow, from Fireware Web UI: You can configure your Firebox as a NetFlow exporter in Fireware v12.3 or higher.įor detailed information about NetFlow, see About NetFlow.
