Table 1–8Barracuda NG Firewall

Module

Description

 

 

Firewall

The detection of large packet sizes (PMTU discovery) did not work in conjunction with local redirection

 

rules. This issue was fixed.

 

 

HTTP Proxy

Infrequently, the Proxy GUI in Barracuda NG Admin was not fed anymore with up-to-date status

 

information due to an issue within the HTTP Proxy module. This issue was fixed.

 

 

Mail Gateway

Due to a database problem, the Mail Gateway erroneously went down on rare occasions and had to be

 

restarted manually. This issue was fixed.

 

 

Network

On VFxxx virtual machines, it was erroneously not possible to select previously configured additional

 

interfaces directly after the virtual machine was installed. This issue was fixed.

 

 

Network

The authentication daemon erroneously crashed when a device tried to authenticate while at the same

 

time leaving the WiFi’s transmission range. This issue was fixed.

 

 

Network

The activation of bonding on a unit could under certain circumstances result in the creation of erroneous

 

MAC mapping tables. This issue was fixed.

 

 

Network

An erroneous match for the priority of a 3G or xDSL routing rule caused previously assigned source

 

addresses to remain part of the source match condition, which was leading to the creation of a stack of

 

rules that eventually exhausted the maximum number of rules. This issue was fixed.

 

 

Network

The IP address for a DHCP link that had been configured to use Dynamic DNS was erroneously not

 

updated as intended. This issue was fixed.

 

 

NG Control Center

In conjunction with different firmware release versions on a Barracuda NG Control Center and its

 

managed units, certain configuration options may erroneously have been unavailable on the NG Control

 

Center, such as e.g. URL filter categories for a 4.2.x cluster on a 5.x NG CC. This issue was fixed.

 

 

NG Control Center

It was erroneously not possible to add a WLAN node to the Repository. Any attempt to do so failed with an

 

error pop-up message saying Copy to Repository Status: Error. This issue was fixed.

NG Control Center

In very rare occasions and only in conjunction with different release versions on an NG CC and its

 

managed units, Barracuda NG Control Center assigned erroneous default NIC driver names to certain

 

managed units. This issue was fixed.

 

 

NG Control Center

Under certain circumstances, Repository directories could erroneously get wrong label names after a

 

migration process. This issue was fixed.

 

 

SNMP Service

Blocked services were through SNMP erroneously indicated as being started. This issue was fixed.

 

 

VPN Service

At very rare occasions, the internet key exchange (IKE) service crashed, resulting in a short service

 

interruption with currently open VPN tunnels, as these tunnels went down and were then automatically

 

re-created.

 

 

VPN Service

NAT traversal did erroneously not work with site-to-site tunnels. This issue was fixed.

 

 

VPN Service

Terminating VPN tunnels via Barracuda NG Admin was on rare occasions leading to a kernel panic. The

 

same problem could also occur in conjunction with Access Control Service connections on certain ports.

 

This issue was fixed.

 

 

VPN Service

The VPN Service occasionally crashed with certificates that contained long subject names. This issue was

 

fixed.
