  • Firewall – Copying access rules with enabled SSL Inspection from firewalls running firmware version 7.2.x to firewalls running firmware version 7.1.0 - 7.1.3 can have a negative impact on SSL Inspection on the destination system.
  • ATP – The "Scan first, then Deliver" option and SMTP-AUTH is not yet supported. [BNNGF-52992]
  • ATP – The "Scan first, then Deliver" option and using an MUA (eMail client) - NGFW - MTA is currently not supported. [BNNGF-52992]

  • ATP – The "Scan first, then Deliver" option with SMTP and VRF is not yet supported. [BNNGF-52992]
  • AWS-Cloud – Deploying AWS Auto Scaling clusters in the US-East-1 region currently fails to create an S3 bucket automatically. Create the bucket manually instead.
  • Certificate Store – When referencing certificates in the Certificate Store from services like SSL Inspection, the reference counter in the Ref By column still shows 0. [BNNGF-50666]

  • Virtual Routing and Forwarding (VRF) – Changing the ID of an active virtual router instance to another ID is currently not supported. Instead, see How to Delete a Virtual Router Instance and How to Configure and Activate a Virtual Router Instance with Hardware, Virtual, VLAN, or Bundled Interfaces.

Current Known Issues Related to the Web Interface for Cloud
  • Azure Cloud – In Azure, after switching from Firewall Admin to the web interface, the connection can become very slow or even time out. [BNNGF-49960]
