These instructions assume:
- The SonicWall device is running SonicOS version 7.0 or higher.
- The date, time and time zone are correctly set on the firewall.
- You have administrative access to the firewall.
- The IP address of your Auvik collector is known.
If you have a shared collector and want to ensure that it receives netflow data to enable TrafficInsights, you will need to add the source IP address as a /32 in order for Auvik to register the flows from that specific address in the TrafficInsights portal. There may be some delay for the shared collector to receive the data after the change.
Note: Even if that source IP address is already being scanned, you must add a /32 targeting only the source IP address, due to some limitations, the collector can’t tell if it should be sent to site A or B.
