To synchronize IPv6 configuration, set Enable IPv6 to Yes on both the units. If the units are in a cluster, the IPv6 configuration does not synchronize if one of the units is IPv6 enabled and the other is disabled. Configuring the Barracuda Web Application Firewall with IPv6 addresses.Before configuring IPv6 Services, read the following: The current firmware release (7.6) provides only basic IPv6 features. The Barracuda Web Application Firewall supports Internet Protocol Version 6 (IPv6) along with its predecessor IPv4.
The double-colon can be used only once to compress an IPv6 address, either in the beginning, middle or end.Įxample: FEDC::FEDC:E4BF:100:10 is equivalent to FEDC:0000:0000:0000:FEDC:E4BF:100:10 IPv6 Support in Barracuda Web Application Firewall These zeros can be further compressed and replaced with double-colon (::) to make IPv6 address notation less cumbersome. The leading zeros can be omitted within each 16-bit hexadecimal block, and written as 0 instead of 0000, 100 instead of 0100 and 10 instead of 0010. IPv6 addresses are represented as eight 16-bit hexadecimal blocks separated by colons (:).Įxample: FEDC:0000:0000:0000:FEDC:E4BF:0100:0010 IPv6 addresses can be associated with one or more interfaces.Version 6 supports varied addressing types (unicast, anycast, multicast, link-local, sitelocal, and global).IPv6 uses 128-bit IP addresses compared to 32-bit IP addresses used by IPv4.
The main advantage of IPv6 is a larger address space than IPv4. IP version 6 (IPv6) is a new version of the Internet Protocol, the successor of IP version 4 (IPv4). This feature is available only with Barracuda Web Application Firewall version 7.6 or higher.
