8.3.0 Release Notes

  • Last updated on

Important Announcements and Notes

Read this section before you continue with the Release Notes below.

Outdated technical features are subject to removal in order to keep the CloudGen Firewall up to date and performing properly. See the following two paragraphs for the features that will be removed in this release and the features that are subject to removal in upcoming releases.

Certain features will be removed completely because they have become technically obsolete; other features have become outdated and will be replaced by improved technology.

Features No Longer Supported as of the 8.3.0 Release

  • Generic Forwarder
    As of 8.3.0, networks that were entered in General Firewall Configuration -> Operational -> Generically Forwarded Networks are no longer supported and will be removed. Networks that are configured in this list will no longer be forwarded by the firewall after updating to release 8.3.0. You must configure a forwarding firewall service with corresponding rules to have this functionality.
  • Protocol 254/FW compression
    Firewall-to-Firewall compression has been discontinued and is no longer configurable. Traffic that was previously configured to use FW-2-FW compression will now be transported uncompressed.

Features that Will Become Obsolete in an Upcoming Release

  • FWAudit
  • WAN Optimization
  • CloudGen Firewall Web UI

Precautionary Security Measures for Control Centers

If you have a Control Center deployed with the CC wizard and there is no ECDSA CC SSH key configured at CC Identity, Barracuda Networks recommends the following to avoid possible security risks:

  1. Manually create a new ECDSA "CC SSH key"
  2. Create a legacy CC SSH key with more than 512 bits

Known Issue for IPS

If you are using IPS and want to continue to do so in firmware 8.3.0, you must deactivate any traffic for UDP.

This is a known issue and will be solved in the upcoming firmware release 8.3.1.

 

Release Notes

Before installing the new firmware version:

Do not manually reboot your system at any time during the update unless otherwise instructed by Barracuda Networks Technical Support. Upgrading can take up to 60 minutes.

What's New in Version 8.3.0

CGF Policy Profiles

On Barracuda CloudGen Firewall version 8.3.0, a new feature has been implemented that allows central management of SD-WAN policies as well as policies for handling different network scenarios and applications. Policy profiles are predefined rules that can be applied to access rules on Control Center-managed or stand-alone firewall units. The Barracuda CloudGen Firewall allows administrators to manage, create, and customize general policies on global, range, cluster, or box level that can then be applied to access rules instead of configuring firewall objects. You can customize default profiles by adding or modifying policies, or create new profiles with explicit policies. This new feature is specifically designed to simplify the handling of policies, especially on a global scale. For more information, see Policy Profiles.

The Barracuda CloudGen Firewall provides the following policies:

SD-WAN Policies

SD-WAN provides multipath VPN tunnels across all providers with redundant, reliable, and fail-safe network connections. The Barracuda CloudGen Firewall provides a predefined default configuration of SD-WAN policies that allows you to use the advantages of SD-WAN immediately, without even having to set up your own configuration. For more information, see How to Create SD-WAN Policies.

Application Policies

Application policies allow administrators to block, allow, or customize traffic for detected applications on a global and local level. Create explicit profiles and policies on the Control Center and assign them to access rules on managed firewalls. For more information, see How to Create Application Policies.

URL Filtering Policies

Barracuda Networks provides a large database for URL filtering. The default action of a policy can be either to block all and define exceptions that are allowed, or to allow all and define exceptions that are blocked. You can customize a URL filtering policy profile to match individual requirements, or you can create explicit policies. For more information, see How to Create URL Filtering Policies.

Malware Protection Policies

Malware protection offers protection against advanced malware, zero-day exploits, and targeted attacks not detected by the Intrusion Prevention System. Scanning is done according to the virus scanner configuration and, if an Advanced Threat Protection (ATP) license is present, also by the ATP engine. For more information, see How to Create Malware Protection Policies.

SSL Inspection Policies

SSL Inspection decrypts inbound and outbound SSL and TLS connections so the Barracuda CloudGen Firewall appliance can allow features, such as Malware Protection and the Intrusion Prevention System (IPS), to scan traffic that would otherwise not be visible to the firewall service. For more information, see How to Create SSL Inspection Policies.

IPS Scanning Policies

The Intrusion Prevention System (IPS) monitors local and forwarding traffic for malicious activities and provides various countermeasures to avert possible network attacks. Create explicit IPS policies to match individual network requirements. For more information, see How to Create IPS Policies.

It is recommended to read the Known Issues section at the bottom of this 8.3.0 Release Notes article ( Known Issues related to CGF Policy Profiles ) before using CGF Policy Profiles.
Barracuda Firewall Admin

Barracuda Firewall Admin has undergone many changes, including those related to the new implementations listed below. The most salient improvements are as follows:

New Network Activation

Activating the network is now supported by two new dialog windows that include user-interface items displayed either statically or dynamically, depending on the context in which the window is displayed:
network_activation_window_new.png
The Soft option will be displayed only in certain required contexts.
fwa_dialog_boxnet_activation_required_after_mip_change.png
For more information, see How to Activate Network Changes.

Automated Session Reconnect

In the Control Center, the Connect button for reconnecting to a lost session has been removed. Reconnecting is now done permanently in the background. Firewall Admin checks the availability and immediately reconnects to an appliance when it becomes available after a previously lost session.
fwa_no_connect_session_button.png

Automated HA Auto Pairing

The HA Auto-Pairing feature has been improved and now supports automated pairing of two Control Centers as well as the automated pairing of managed firewalls.

For more information, see HA Auto-Pairing and How to Enable HA Auto-Pairing for Two Managed Firewalls.

C2S TINA VPN Improvements

Unlike before, when network routes could only be entered as an IP address, they can now be entered as a domain in the group policies. These domains will be resolved by the CloudGen Firewall when a client connection to the firewall is established using Barracuda Network Access Client. In addition, a description can now be added to the domain names. This feature also is available when creating licenses for VPN users or when creating network routes for a template.
C2S_FQDN_for_network_routes.png

On the NAC client site, these added domains will be introduced to Windows machines as routes using their related IP addresses. In order to log the DNS calls to resolve the introduced routes, some new logs have been added to the NAC client.

This feature requires Barracuda Network Access Client version 5.3 for Windows. For more information, see Release Notes - Barracuda NAC/VPN Client 5.3 for Windows.

In order to avoid fragmented IP packets, a new transport mode has been added to the Barracuda Network Access Client > Machine VPN Profile, tab General, Tunnel Settings > Tunnel Mode. This mode starts the authentication and authorization messaging using the TCP protocol and then switches to the UDP protocol for exchanging data streams. For more information, see How to Create VPN Profiles.

C2S_tunnel_mode_hybrid_tcp_udp.png

The MTU size can now be managed centrally in the VPN Settings. Unlike before, when the MTU size had to be configured individually on each client, clients will now receive the centrally managed MTU value when connecting to the VPN server.
C2S_MTU_size_for_clients_02.png

In the Barracuda encryption settings at CONFIGURATION > Configuration Tree > Box > Assigned Service > VPN Service > Client to Site-VPN, tab External CA > Barracuda, window Barracuda Settings, a check box has been added that limits connections to the VPN server only for Windows clients that have disk encryption enabled.

C2S_disk_encryption.png

For the VPN server certificate, you can now configure a certificate chain.

C2S_certificate_chain.png

For importing a certificate or a certificate chain, a password query has been implemented that displays a dialog window in the following three cases:

  1. When the file to be imported is encrypted.
  2. When parsing the file is not possible, e.g., due to faulty file content.
  3. When the file to be imported has a different file extension, e.g., 'p12', ...

vpn_settings_password_for_certs.png

And finally, two new encryption methods, AES-GCM and AES-CTR, can now be configured in the client-to-site VPN Settings.

ConfTemplate Editor

The ConfTemplate Editor has been improved and now also includes an area for displaying help information for ConfUnits. This area is located to the right of the edit area and includes a drop-down list to select the requested information. Example code snippets are also part of the help menu and can be copied and pasted into the editor. For a better overview, disabled instances are now displayed in gray in the ConfTemplate Manager. When editing is completed, clicking the OK button verifies the data in the editor and closes the window if no errors are found.

ConfUnits

ConfUnits have been updated, whereby some ConfUnits have been replaced and other units have been extended. There are two groups of ConfUnits:

  • CGF ConfUnits currently include: cgfCore, cgfDhcpSubnet, cgfDns, cgfFirewall, cgfGtiTunnel, cgfIpv4Route, cgfIpv6AdditionalAddress, cgfIpv6Route, cgfIpv6SharedNetwork, cgfRemoteManagementTunnel, cgfRepositoryLink, cgfSharedNetwork, cgfSiteSpecificObject.
  • FSC ConfUnits currently include: fscAdvanced, fscConfEntry, fscContainer, fscCore, fscDhcpAdvanced, fscFirewall, fscLan, fscVpn, fscWan, fscWifi, fscWwan.
IPS

As of firmware 8.3, the CloudGen Firewall includes a new IPS system. The replacement of the former IPS system with the new implementation is fully transparent to the user. Any differences will appear at unobtrusive locations in the user interface when configuring the IPS system.

The new IPS system will operate using new IPS signatures. For this reason, the signature IDs (which are synonymous with the IPS rule sets) of the former IPS system (prior to firmware release 8.3.0) are no longer valid and will be dropped when updating to firmware release 8.3.0. For more information, see also 8.3.0 Migration Notes.

The signature database contains two rule sets:

  • Performance Optimized
  • Coverage Optimized

These two rule sets are essentially the same; however, the Performance Optimized rule set only contains signatures with priority "Critical" and "High".

IPS_conf_screen.png

Details on the operation of the IPS in case problems arise can be inspected in the log file box_Firewall.log.

IPv6 Enhancements

In order to fully support firewalling for IPv6 addresses, the range of functions was ported from IPv4 to IPv6 on the CloudGen Firewall. All configuration options - except IPv6 WINS, which has no relevance on IPv6 - are covered in the user interface in Firewall Admin, where applicable, and can be used transparently as with IPv4.

There are certain features that do not yet work for IPv6 and will be addressed in the upcoming firmware release 8.3.1:

  • Functionality related to authentication, e.g., user matching in IPv6 rules, IPv6 address/port-based authentication, ATP quarantine.
  • ProxyARP-like functionality for IPv6, e.g., neighbor discovery proxy.
  • Application-based provider selection.
  • Multicast firewall rules.
  • Source-based routing.
  • Certain services do not yet fully support IPv6, e.g., HTTP-proxy, DHCP, NTP, IPFIX, SIP-proxy, and more.
  • Application Rules: while there are still two separate access rule sets for IPv4 and IPv6, there is only one application rule set that covers both IPv4 and IPv6 addresses. This means that application rules can match both IP versions, depending on the rule's source and destination.
OpenSSL 3 Update - FIPS

Because OpenSSL 1.0 is no longer supported, it has been replaced by OpenSSL 3. OpenSSL 3 supports running FIPS and non-FIPS sessions simultaneously but can also operate in only FIPS or non-FIPS mode. OpenSSL 3 is fully transparent to the user.

With the update of OpenSSH to version 8.8 in CGF firmware 8.3.1, RSA signatures using SHA1 have been disabled by default. When using an up-to-date client, this should not be an issue because it will automatically use another hashing algorithm. However, when using older clients, SSH logins might suddenly no longer work after the update. If this happens, it is recommended to first try with Firewall Admin and, if that still works, to check if updates to the SSH client being used are available.

REST API

The REST API has been updated and now includes the latest implementations.

The endpoints referencing an explicit virtual server were marked as deprecated in 8.2.0 and have been removed in the 8.3.0 release. Using deprecated endpoint messages are logged in the restd log file. The new service container API can be used with /rest/control/v1/service-container/...

You can now configure policies used by firewall rules via REST.

Configuration endpoints are now available:

  • CC - create new managed box (with or without ConfTemplate)
    /rest/cc/v1/ranges/{range}/clusters/{cluster}/boxes
  • CC - Site-specific objects
    /rest/cc/v 1/config/ranges/{range}/clusters/{cluster}/boxes/{box}/service-container/{service}/site-specific-objects/{name}
  • CC - Repository Links
    /rest/cc/v1/config/ranges/{range}/clusters/{cluster}/boxes/{box}/repository/link
  • CC - Remote Management Tunnel
    /rest/cc/v1/config/ranges/{range}/clusters/{cluster}/boxes/{box}/network/management-tunnel
  • CC/Box - Authentication - Local/LDAP
  • CC/Box - Create/Update/Remove Service
    /rest/cc/v1/ranges/{range}/clusters/{cluster}/boxes/{box}/service-container
    /rest/config/v1/service-container
  • CC/Box - IPv4/IPv6 Route Config
    /rest/cc/v1/config/ranges/{range}/clusters/{cluster}/boxes/{box}/network/route/v4
    /rest/cc/v1/config/ranges/{range}/clusters/{cluster}/boxes/{box}/network/route/v6

For more information, see https://campus.barracuda.com/product/cloudgenfirewall/api.

VPN IKEv2

The VPN settings now contain a new configuration setting called IKEv2 Suppress Network Change Events. When the check box for this parameter is selected, network/interface changes that may cause an automatic reconnect of the VPN tunnel will be ignored. For more information, see IPsec Settings.

Known Issues

Known Issues Related to CGF Policy Profiles
  • IMPORTANT – Policy profiles cannot be used on a VPN concentrator or Secure Access Controller!
  • Firewall – If a VPN TINA tunnel transport over a specific ISP goes down, the Internet traffic over the same ISP link will not work either.    [BNNGF-81749]
  • Provider class in boxnet must not be changed "afterwards", unless existing VPN tunnels are reconfigured accordingly.
  • There is currently no VRF support for policies in 8.3.0.
  • Fallback (on-demand) does not always work in combination with explicit SD-WAN policy.    [BNNGF-81805]
Known Issues Related to Other Topics
  • Azure – OMS is currently not supported on CC-managed boxes.
  • Currently, no RCS information is logged for Named Networks.    [BNNGF-47097]
  • Barracuda Firewall Admin – FW Admin 8.x fails to configure DNS 7.x correctly.    [BNNGF-77636]
  • Barracuda OS – Gateway probing continues after route got removed.    [BNNGF81668]
  • Barracuda OS –  The IPv6 route management of controld interferes with SLAAC.    [BNNGF-81574]
  • The learn-only mode for OSPF is not working as expected.    [BNNGF-65299]
  • Control Center – After configuration and activation of the SAML/ADFS authentication, the SP metadata is not set on the Control Center.     [BNNGF-76521]
    As a workaround, complete the following steps: 1. Connect to the box.  2. Configure SAML by doing an Emergency Override.
  • F183R – The F183R freezes when starting the telemetry process if an M40 modem is connected. Workaround: if you disconnect the modem or disable telemetry, the problem will not occur.
  • Firewall – A Connection Object is not applied if it uses network interfaces.    [BNNGF-83146]
    As a workaround, also add the interface to the Failover and Load Balancing section and remove it again as soon as a fix is available.
    This issue affects release 8.3.0 and will be fixed in the upcoming firmware release 8.3.1.
  • If you enable WanOPT on a tunnel, TCP traffic is no longer forwarded. However, ping works as expected.    [BNNGF-82256]
  • IPS – Using IPS for UDP in firmware 8.3.0 will break the firewall.    [BNNGF-83189]
