The management interface can receive a dynamic IPv6 address assignment by using
either stateful DHCPv6 or SLAAC with stateless DHCPv6.
Manually configuring static IPv6 addresses on a firewall's management (MGT) interface
can be time-consuming and complex, especially in large, dynamic network
environments. To solve this, your Next-Generation Firewall (NGFW) now supports
dynamic IPv6 address assignment on its management
(MGT) interface. This makes it easier to insert and manage the firewall
in an IPv6 network.
The firewall's MGT interface can dynamically receive its IPv6 address from a
stateful DHCPv6 client or an IPv6 stateless address autoconfiguration
(SLAAC) client. A stateful client receives its address and configuration
information from a DHCPv6 server. A stateless client, on the other hand,
automatically generates its own address. This is especially helpful in environments
with a large number of endpoints because it avoids the need for a DHCPv6 server to
store dynamic state information about each client.
The firewall can also dynamically learn its default gateway from the router’s Router
Advertisement (RA) message. This option is available even when you configure a
static IPv6 address on the MGT interface. This new flexibility allows you to choose
from various combinations for the MGT interface and its default gateway, including
both static and dynamic address assignments.
There is a known issue where the firewall prefers a DHCPv6
address over a SLAAC address if a DHCPv6 server is present, even when configured for
SLAAC. This occurs when the Autonomous (a) flag is set in the Router Advertisement
(RA) message.
