The screen adjusts:
3. Configure the fixed IPv6 addresses for the WAN connection.
The following fields are included in this screen:
• 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, which is
supposed to be on 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 Internet Setup on page 23.)
4. Specify how the modem router assigns IPv6 addresses to the devices on your home
network (the LAN) by selecting one of the following radio buttons:
• Use DHCP Server.
This method passes more information to LAN devices, but some
IPv6 systems might not support the DHCv6 client function.
• Auto Config.
This is the default setting.
5. 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 ID here, the modem router generates one automatically from its
MAC address.
6. Click the Apply button.
