Set up the FortiAnalyzer-BigData network

To set up the network for FortiAnalyzer-BigData, users need to connect either a 10GE link with SFP, or 40GE link with QSFP, from Switch Module #2 to your public access switch, and them set up the external IP address via the FortiAnalyzer-BigData GUI.

To set up the FortiAnalyzer-BigData network:

1. From the FortiAnalyzer-BigData GUI, go to System Settings > Network.
2. Change the IP Address/Netmask field to your internal network.
   This is the address of the FortiAnalyzer-BigData Main host, which is responsible for collecting the log and serving the GUI for FortiView, LogView, Reports etc.
3. Keep the default Administrative Access settings.
4. Specify a Default Gateway.
5. Click Cluster Management to configure the network for the FortiAnalyzer-BigData Cluster Manager.
   
   1. In the Cluster Management page, change the IP Address/Netmask field to your internal network.
      This field is different from the one used in step 2. This IP Address is for the FortiAnalyzer-BigData Security Event Manager Controller.
   2. Configure the Gateway field as needed.
      This address is usually the same as the Default Gateway field in step 4.
      
   3. Click OK to save your changes.
6. Click Apply to save your change.
7. From your management computer, change the IP Address/Netmask accordingly to reconnect it to FortiAnalyzer-BigData.
