Issues resolved by hotfixes
The following hotfixes have been released for firmware version 6.2.1
Hotfix 849 - KRACK Attack
- Security fix for the WPA2 vulnerability.
- Azure: If the MAC Address of the network interface changes between the time the firewall is deployed until it is licensed via Barracuda Activation in a Control Center, the wrong MAC address is used to activate the license.
- 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.
- SSL VPN: 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.
- 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.
- IKEv2: You can only use MSAD authentication schemes for client-to-site IKEv2 IPsec VPNs.
- 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: The mobile navigation bar is missing from servers entered in the Allowed Hosts.
- 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 already 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 NextGen Admin: SPoE does not work if an IPv6 virtual server IP address is used.
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/188.8.131.52-9ph5.4.3.06.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.
VPN: Rekeying does not currently work for IPsec Xauth VPN connections. The VPN tunnel terminates after the configured rekeying time and needs to be re-initiated.
- Global File Content, User Agent, and Schedules objects are not available as cluster and range objects.
