How to enable flow on your Sophos XG firewall

Follow

This sample configuration is based on a Sophos XG firewall. Other models may have slight configuration variations.

  4. Enter port 20013 as the Netflow server port.
  5. Click Apply.

  1. Go to Firewall Netflow > Rule.
  2. Select IPv4.
  3. Expand Advanced Settings.
  4. Enable Log Firewall Traffic.
  5. Click OK.
