Configure the fixed IPv6 addresses for the WAN connection:

•

IPv6 Address/Prefix Length

. The IPv6 address and prefix length of the router WAN

interface.

•

Default IPv6 Gateway

. The IPv6 address of the default IPv6 gateway for the router’s

WAN interface.

. The primary DNS server that resolves IPv6 domain name

records for the router.

•

Secondary DNS Server

. The secondary DNS server that resolves IPv6 domain

name records for the router.

Note:

If you do not specify the DNS servers, the router uses the DNS servers

that are configured for the IPv4 Internet connection on the Internet

Setup page. (See

Manually Set Up the Internet Connection

on

page

This setting specifies how the router assigns IPv6 addresses to the devices on your home

network (the LAN).

Set Up an IPv6 DHCP Internet Connection



To set up an IPv6 Internet connection with a DHCP server:

1.

Launch an Internet browser from a computer or wireless device that is connected to the

network.

2.

Type

http://www.routerlogin.net

or

.

A login window opens.

3.

Enter the router user name and password.

The user name is

Select

ADVANCED > Advanced Setup > IPv6

.

The IPv6 page displays.

5.

In the

Internet Connection Type

menu, select

DHCP

.

The router automatically detects the information in the following fields:

•

Router’s IPv6 Address on WAN

. This field shows the IPv6 address that is acquired

for the router’s WAN (or Internet) interface. The number after the slash (/) is the length

of the prefix, which is also indicated by the underline (_) under the IPv6 address. If no

address is acquired, the field displays Not Available.

•

Router’s IPv6 Address on LAN

. This field shows the IPv6 address that is acquired

for the router’s LAN interface. The number after the slash (/) is the length of the prefix,

which is also indicated by the underline (_) under the IPv6 address. If no address is

acquired, the field displays Not Available.

6.

Select an IPv6 Domain Name Server (DNS) Address radio button:

. If you know that your ISP requires specific servers, select

this option. Enter the IP address of your ISP’s primary DNS server. If a secondary

DNS server address is available, enter it also.

7.

(Optional) In the

User Class (If Required)

field, enter a host name.

Most people can leave this field blank, but if your ISP gave you a specific host name,

enter it here.

8.

(Optional) In the

Domain Name (If Required)

field, enter a domain name.

You can type the domain name of your IPv6 ISP. Do not enter the domain name for the

IPv4 ISP here. For example, if your ISP’s mail server is mail.xxx.yyy.zzz, type xxx.yyy.zzz

as the domain name. If your ISP provided a domain name, type it in this field. For

example, Earthlink Cable might require a host name of home, and Comcast sometimes

supplies a domain name.

Enter the settings that your service provider gave you.

If your service provider gave you only one user name and password, the service provider

most likely supports dual stack PPPoE (a single PPP session). If the service provider

gave you two user names and passwords for IPv4 and IPv6, then the router must use

different PPP session.

•

To use separate PPP sessions (the default setting), leave the

This is usually the name that you use in your email address. For example, if your main

mail account is [email protected], you would type JerAB in this field. Some ISPs (like

If your ISP did not provide a service name, leave this field blank.

Note:

The default setting of the

provide a steady IPv6 connection. The router never terminates the

connection. If the connection is terminated, for example, when the

modem is turned off, the router attempts to reestablish the connection

immediately after the PPPoE connection becomes available again.

Change the MTU Size

The maximum transmission unit (MTU) is the largest data packet a network device transmits.

When one network device communicates across the Internet with another, the data packets

travel through many devices along the way. If a device in the data path uses a lower MTU

setting than the other devices, the data packets must be split or “fragmented” to

accommodate the device with the smallest MTU.
