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 that your ISP provided to you.
• Default IPv6 Gateway. The IPv6 address of the default IPv6 gateway for the modem
router’s W
AN interface that your ISP provided to you.
• Primary DNS. The primary DNS server that resolves IPv6 domain name records for
the modem router that your ISP provided to you.
• Secondary DNS. The secondary DNS server that resolves IPv6 domain name
records for the modem router that your ISP provided to you.
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 an ADSL Internet
Connection on page 47
).
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 DHCPv6 client
function. This is the default setting.
• Auto Config.
The 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.
