Barracuda Networks 5.0.3 manual Module, Description

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.
