What´s new in version 7.0.0
VPN service IPv6 support
You can now connect two locations using IPv6 addresses via site-to-site VPN with either the TINA, IPsec IKEv1, or IKEv2 VPN protocols. The GTI Editor and Traffic Intelligence also added support for IPv6 transports, allowing you to configure and use a mix of IPv4 and IPv6 transports. Client-to-site and remote management tunnels can also connect using IPv6 addresses. Traffic passing through the tunnel is IPv4-only.
DNS sinkhole in the Firewall
DNS traffic handled by the Firewall service is monitored and, if a domain is found that is considered to be malicious, the A and AAAA DNS response is replaced by fake IP addresses. An access rule blocks the clients from accessing the fake IP addresses and logs the attempt in the Threat Scan and Firewall Monitor.
Connection object and load balancing improvements
You can now create custom connection objects with failover and/or load balancing of up to eight connections. For applications requiring sticky sessions, the Source IP Hash load balancing policy is added. This load balancing policy uses the hash of the source IP address to determine the egress interface. This setting is persistent as long as the source IP address of the client is not changed. Failover alternatives can now also use the Original IP and Dynamic NAT policies.
Barracuda Network provides you with a Rest API for the F-Series Firewall, allowing you to integrate the firewall into your applications. See our Rest API developer documentation for more information.

Firmware update directly from UPDATES element
You can download and install updates and hotfixes directly from the UPDATES element on the NextGen Admin dashboard for stand-alone firewalls. For managed firewalls, the update or hotfix package is downloaded directly to the Control Center and then distributed to the managed firewalls.
IPv6 support for hostname network objects and custom external network objects
It is now possible to resolve IPv6 addresses of FQDNs of hostname network objects. Importing IPv6 addresses into custom external network objects is also supported.
The NAT Information view allows you to see the NAT operations configured in the action and connection method of the access rules. To access the NAT view, click the icon and select Show NAT information.
For more information, see
Bulk import for URL Filter policy objects
Block and allows lists for URL Filter policy objects can now be entered using bulk edit. This allows you to copy/paste a file containing a large number or domains without having to enter them individually.
External logfile storage
You can now configure log cycling to move your logfiles to an external USB storage device attached to your firewall.
SSL VPN web portal redesign
The web portal is redesigned to give desktop and mobile devices a single responsive interface. The web portal is designed to automatically display a version customized for the device type you are using.
SSL VPN tunneled web apps
A tunneled web app uses an SSL tunnel established by CudaLaunch to connect to a web server behind the firewall. The user's browser connects to a localhost address (e.g.,
http://localhost:5678 ). A direct connection to the resource located behind the SSL VPN is then established through the SSL tunnel. This type of web app will only work as long as all links stay on the same destination host; it does not modify the data stream.
SSL VPN Native Apps
Some tasks require the use of client-server applications. To connect with a service behind the SSL VPN service on the F-series Firewall, CudaLaunch establishes a secure tunnel and then automatically launches the locally installed application. The connection is terminated if the session is closed or times out.
CudaLaunch 2.0 for Windows, macOS, iOS, and Android is an update for the app that offers secure remote access to your organization's applications and data from mobile devices. CudaLaunch 2.0 now also supports Generic Tunnels and Tunneled Web Apps.
Retrieve PAR file during deployment using Azure and AWS CloudFormation templates
If you are using the NextGen Control Center either on-premises or in the cloud, you can modify your Azure or AWS CloudFormation templates to retrieve the PAR file for the new F-Series Firewall VM directly from the Control Center during deployment. The getpar script uses either CC admin credentials or a shared secret to authenticate. Licenses that are already installed on PAYG firewall Instances are pushed to the Control Center before retrieving the PAR file, whereas BYOL images use the licenses configured on the Control Center.

High availability cluster in AWS
Deploy a Barracuda NextGen Firewall F-Series HA cluster in the Amazon AWS Cloud to ensure that your AWS resources are always available. Cloud Integration allows the firewall to rewrite the AWS route table to always use the active firewall instance. Incoming traffic can be directed to the active firewall by either Amazon Load Balancer for TCP connections or the DNS-based Route 53.
Azure Cloud Integration – IP Forwarding protection
Cloud Integration for F-Series Firewall and Control Center VMs allows the firewall to connect to the Azure service fabric and monitor and, if necessary, correct the IP Forwarding setting of the NIC attached to the VM.
Cloud information dashboard element
F-Series Firewalls deployed in Azure or AWS now display additional information in the cloud information element on the General tab of the dashboard.
Barracuda NextGen Remote for Apple iOS provides system administrators easy remote access to their F-Series Firewalls and Control Centers through their iOS device. Barracuda NextGen Remote added support for push notifications for events.
UMTS/3G modem and link selection support for SC1
The NextGen Firewall SC1 now supports WAN connections using the Barracuda M11 3G/UMTS modem. Link selection allows you to configure a fallback connection for your Secure Connector. When the primary interface is down, traffic is routed over the backup interface to the Secure Access Concentrator. By default, the gateway of the interface is probed every five seconds, but you can also configure an explicit probing target.

Hotfix 848 - KRACK Attack
- Security fix for the WPA2 vulnerability.
- URL Filter: It is not possible to establish WebEx sessions when the URL Filter is enabled on the matching access rule.
- IPsec IKEv1 IPv6: It is not possible to use hostnames as the remote gateway.
- IPsec IKEv1 IPv6: It is not possible to use a dynamic local gateway.
- IPsec IKEv2: It is not possible to establish a VPN tunnel if the active partner uses a dynamic IP address.
- IPsec IKEv2: When using a dynamic local gateway NAT Traversal is not possible.
- TINA IPv6: It is not possible to use proxies for TINA VPN tunnels using IPv6.
- SSH: There is no sshd listener for IPv6 management IP addresses.
- NextGen Admin: IPv6 listeners are not displayed in the Info dialog on the CONTROL > Resources page.
NextGen Admin: The activation dialog only accepts: A-Z, a-z, 0-9 and spaces.
- OSPF: Enabling OSPF through the Run OSPF Router setting currently has no effect on freshly installed 7.0.0 firewalls. Enable OSPF by entering a dummy IP address in the Summary Range IP/ Mask list of the OSPF Area Setup.
SSL VPN Network Places: Some modern browsers such as Chrome and Firefox no longer support Java applets. Instead, use browsers with Java applet support, such as Internet Explorer or Safari.
- VMware: Network interfaces using the VMXNET3 driver do not send IPsec keep alive packets unless TX checksumming is disabled for the interface (ethtool -K INTERFACE tx off).
- URL Filter: F-Series Firewalls running 6.2.0 or higher that are managed by a Control Center using firmware 6.0.X or 6.1.X must complete a dummy change in the security policy whenever enabling/disabling the URL Filter in the General Firewall Settings.
- Azure: After updating a firewall using Azure UDR via Azure Service Manager, the Deployment Type may be displayed incorrectly as y. This does not affect updating Azure UDR routes.
- IKEv2: Disabling a site-to-site tunnel on the VPN > Site-to-Site page is not possible.
- IKEv2: Changing a setting for an IKEv2 tunnel disabled in the configuration causes all active IKEv2 tunnels to initiate a re-keying.
- IKEv2: Client certificate authentication for client-to-site IKEv2 IPsec VPNs requires X509 Certificate to be enabled in the VPN Settings. Enabling this setting requires all VPN group policies to use client certificate authentication.
- IKEv2: After a restart, the Last Access and Last Duration time displayed for site-to-site IKEv2 IPsec tunnels is not reset.
- IKEv2: Using a hostname or subnets as Remote Gateway is currently not possible.
- IKEv2: Using pre-shared keys with IKEv2 client-to-site VPNs is not possible.
- IKEv2: Using X509 Subject Policy in a client-to-site Group VPN Settings is not possible.
- IKEv2: Changing client-to-site minimum and maximum lifetime values has no effect.
- IKEv2: Connecting to an IKEv2 IPsec client-to-site VPN using iOS or Android devices is not possible.
- Azure Control Center: On first boot "fatal" log messages may occur because master.conf is missing. These log messages can be ignored.
- IKEv1 IPsec: When using 0.0.0.0 as a local IKE gateway, you must enable Use IPsec Dynamic IPs and restart the VPN service before a listener on 0.0.0.0 is created.
- HTTP Proxy: Custom block pages do not work for the HTTP Proxy when running on the same NextGen F-Series Firewall as the Firewall service. This issue does not occur when running the HTTP Proxy service on a second NextGen F-Series Firewall behind the NextGen F-Series Firewall running the Firewall service.
- SSL VPN: Favorites are not included in the PAR file.
- SSL VPN: Text fields do not accept the
- SSL VPN: User Attributes do not support UTF-8.
- SSL VPN: The allowed host filter path must be unique.
- Safe Search: In some cases, YouTube safety mode does not work when logged in with a Google account.
- Safe Search: If Safe Search is enabled, it is not possible to log into YouTube when cookies are disabled.
- VPN Routing: When a duplicate route to an existing VPN route in the main routing table is announced to the NextGen Firewall F-Series via RIP, OSPF or BGP, a duplicate routing entry is created and the route that was added last is used.
VPN Routing: Creating a direct or gateway route with the same metric and destination as a VPN route in the main routing table results in duplicate routes. The route added last is used.
HTTP Proxy: Custom Cipher String and Allow SSLv3 settings only apply to reverse proxy configurations.
CC Wizard: The CC Wizard is currently not supported for Control Centers deployed using Barracuda F-Series Install.
ATD: Only the first URL in the Quarantine Tab that leads to a quarantine entry is displayed, even if the User and/or IP address downloaded more than one infected file. This can be dangerous if the first downloaded file is a false-positive.
Barracuda OS: Provider DNS option for DHCP connections created with the box wizard must be enabled manually.
Terminal Server Agent: It is not currently possible to assign connections to Windows networks shares to the actual user.
Firmware Update: Log messages similar to
WARNING: /lib/modules/18.104.22.168-9ph5.4.3.06.x86_64/kernel/drivers/net/wireless/zd1211rw/zd1211rw.ko needs unknown symbol ieee80211_free_hwmay appear while updating, but can be ignored.
Attention: Amazon AWS/Microsoft Azure: Performing Copy from Default of Forwarding Firewall rules currently locks out administrators from the unit and requires a fresh installation of the system.
Application Control and Virus Scanning: Data trickling is only done while the file is downloaded, but not during the virus scan. This may result in browser timeouts while downloading very large files.
Application Control and Virus Scanning: If the Content-Length field in HTTP headers is missing or invalid, the Large File Policy may be ignored.
Application Control and Virus Scanning: In very rare cases, if the SSL Interception process is not running, but the option Action if Virus Scanner is unavailable is set to Fail Close, a small amount of traffic may already have passed through the firewall.
Application Control and Virus Scanning: In rare cases, Google Play updates are sometimes delivered as partial updates. These partial updates cannot be extracted and are blocked by the virus scanning engine. The engine reports The archive couldn't be scanned completely. Either create a dedicated firewall rule that does not scan Google Play traffic, or set Block on Other Error in Avira Archive Scanning to No.
Barracuda OS: Restoring units in default configuration with par files created on a Control Center may result in a corrupt virtual server. Instead, copy the par file to opt/phion/update/box.par and reboot the unit.
