• MAC Address: Enter the MAC address in the format xx:xx:xx:xx:xx:xx where
x is a number from 0 to 9 (inclusive) or an alphabetical letter between A and
F (inclusive), for example, 01:23:45:67:89:ab.
• Zone: Maps the secondary WAN to an untrusted zone. The WAN zone is the
default unstrusted zone. Click Create Zone to create other untrusted zones.
See Configuring the Zones, page 127.
STEP 4 In the IPv6 tab, specify the IPv6 addressing settings for the secondary WAN
connection if you enable the IPv4/IPv6 mode.
• IP Address Assignment: Choose Static IP if your ISP assigned a fixed
(static or permanent) IP address. If you were not assigned a static IP address,
choose SLAAC.
- 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.
Primary DNS Server: 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.
