- NG Control Center: Network > Azure Advanced Networking is displayed in a 6.1 cluster even if the managed NG Firewall is running version 6.1.1 or 6.1.0 that does not support this feature.
- HTTP Proxy: Custom block pages do not work for the HTTP Proxy when running on the same NG Firewall as the Firewall service. This issue does not occur when running the HTTP proxy service on a second NG Firewall behind the NG 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.
- Safe Search: Safe Search is not enforced by Bing when using HTTP.
- VPN Routing: When a duplicate route to an already existing VPN route in the main routing table is announced to the NG Firewall 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 NG Control Centers deployed using NG 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.
- Firewall: It is not possible to join a join.me session if SSL Interception and Virus Scanning is enabled in the matching access rule.
- Firewall: Using SSL Interception in combination with URL Filtering and category exemptions may result in degraded performance.
- NG 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/22.214.171.124-9ph5.4.3.06.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 2.0 and Virus Scanning: Data Trickling is done only while the file is downloaded, but not during the virus scan. This may result in browser timeouts while downloading very large files.
- Application Control 2.0 and Virus Scanning: If the Content-Length field in HTTP headers is missing or invalid, the Large File Policy may be ignored.
- Application Control 2.0 and Virus Scanning: It is not currently possible to perform virus scanning for chunked transfer encoded HTTP sessions such as media content streaming. Barracuda Networks recommends excluding such traffic from being scanned.
- Application Control 2.0 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 2.0 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 an NG 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.
High Availability: IPv6 network sessions might not be established correctly after an HA failover.
