IP Address Assignment:
Choose
Static IP
if your ISP assigned a fixed

choose

SLAAC:
If you choose SLAAC, the security appliance can generate its
own addresses using a combination of locally available information and
information advertised by routers.
-
Static IP:
If your ISP assigned a static IPv6 address, configure the IPv6
WAN connection in the following fields:
IPv6 Address:
Enter the static IP address that was provided by your ISP.
IPv6 Prefix Length:
The IPv6 network (subnet) is identified by the initial
bits of the address called the prefix. All hosts in the network have the
identical initial bits for their IPv6 address. Enter the number of common
initial bits in the network’s addresses. The default prefix length is 64.
Default IPv6 Gateway:
Enter the IPv6 address of the gateway for your
ISP. This is usually provided by the ISP or your network administrator.

Enter a valid IP address of the primary DNS Server.
Secondary DNS Server (Optional):
Optionally, enter a valid IP address
of the secondary DNS Server.
