Current Known Issues
  • Jun 2018: 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 negative impact on SSL Inspection on the destination system.
  • Feb 2018: The ZTD daemon on the NGF Control Center rarely runs into a condition, where it continuously polls the ZTD service for new access tokens. This may leave ZTD unusable and can be recognized in the ZTD map’s feedback area, where tokens become invalid and immediately get renewed. Restarting the ZTD process via kill -9 ztd on the console temporarily resolves this issue. Alternatively log into the ZTD web UI > Settings page and delete the authentication token.
  • Nov 2017: VLANs – Transferring data over configured VLAN interfaces of a NextGen Firewall F180 or F280b can fail even if the MTU size is changed. BNNGF-46289
  • September 2017: Azure ASM – NextGen Firewalls deployed using Azure Service Manager now show the status running after deployment in the Azure portal. This does not affect the firewall VM's functionality. BNNGF-48296
  • June 2017: Traffic Intelligence – Dynamic Bandwidth and Latency Detection currently does not work on VPN transports using an IPv6 envelope. BNNGF-47114
  • June 2017: Control Center – Importing an archive.par that does not contain a CC database dump fails if the CC database is enabled. BNNGF-46601
  • Oct 2016: Application Based Routing – Streaming web applications such as WebEx, GoToMeeting, or BitTorrent always use the default connection configured in the application-based provider selection object. BNNGF-42261
  • Sept 2016: VMware – Network interfaces using the VMXNET3 driver do not send IPsec keepalive packets unless TX checksumming is disabled for the interface (ethtool -K INTERFACE tx off). BNNGF-38823
  • Sept 2016: Azure – After updating a firewall using Azure UDR via Azure Service Manager, the Deployment Type might be displayed incorrectly as y. This does not affect updating Azure UDR routes.
  • Sept 2016: IKEv1 IPsec – When using as a local IKE gateway, you must enable Use IPsec Dynamic IPs and restart the VPN service before a listener on is created.
  • Sept 2016: HTTP Proxy – Custom block pages do not work for the HTTP Proxy when running on the same NextGen Firewall as the Firewall service. This issue does not occur when running the HTTP Proxy service on a second NextGen Firewall behind the NextGen Firewall running the Firewall service.
  • Sept 2016: VPN Routing – When a duplicate route to an existing VPN route in the main routing table is announced to the NextGen Firewall via RIP, OSPF, or BGP, a duplicate routing entry is created and the route that was added last is used.
  • Sept 2016: Terminal Server Agent – It is not currently possible to assign connections to Windows network shares to the actual user.
  • Mar 2016: SSH – There is no sshd listener for IPv6 management IP addresses. BNNGF-37403
  • Feb 2016: Azure Control Center – On first boot, "fatal" log messages may occur because master.conf is missing. These log messages can be ignored. BNNGF-36537
  • Feb 2015: CC Wizard – The CC Wizard is not currently supported for Control Centers deployed using Barracuda F-Series Install. BNNGF-28210
  • Dec 2015: URL Filter – It is not possible to establish WebEx sessions when the URL Filter is enabled on the matching access rule. BNNGF-35693
  • Nov 2015: IKEv2 – Using pre-shared keys with IKEv2 client-to-site VPNs is not possible. BNNGF-34874
  • Nov 2014: Barracuda OS – Provider DNS option for DHCP connections created with the box wizard must be enabled manually. BNNGF-26880
