7. Configure the fixed IPv6 addresses for the WAN connection:
• IPv6 Address/Prefix Length
. The IPv6 address and prefix length of the modem
router WAN interface.
• Default IPv6 Gateway. The IPv6 address of the default IPv6 gateway for the modem
router’
s WAN interface.
• Primary DNS Server. The primary DNS server that resolves IPv6 domain name
records for the modem router.
• Secondary DNS Server. The secondary DNS server that resolves IPv6 domain
name records for the modem router.
Note: If you do not specify the DNS servers, the modem router uses the DNS
servers that are configured for the IPv4 Internet connection on the
Internet Setup screen (see Manually Set Up the Internet Connection
on page 45
).
8. Select
an IP Address Assignment radio button:
• Use DHCP Server. T
he modem router assigns IPv6 addresses to the devices on your
home network (the LAN) through a DHCP server. This method passes more information
to LAN devices, but some IPv6 systems might not support the DHCv6 client function.
This is the default setting.
• Auto Config.
T
he modem router automatically configures its IPv6 address based on the
IPv6 protocol.
9. In the IPv6 Address/Prefix Length
fields, specify the static IPv6 address and prefix length
of the modem router’s LAN interface.
If you do not specify an address here, the modem router generates one automatically
from its MAC address.
10. Specify the IPv6 filtering mode:
• Secured. In secured mode, the modem router inspects both TCP and UDP packets.
• Open
. In open mode, the modem router inspects UDP packets only.
This is the
default mode.
