This setting specifies how the router assigns IPv6 addresses to the devices on your home network (the LAN).
10.(Optional) Select the Use This Interface ID check box and specify the interface ID to be used for the IPv6
address of the router’s LAN interface.
If you do not specify an ID here, the router generates one automatically from its MAC address.

Set Up an IPv6 6rd Internet Connection
The 6rd protocol makes it possible to deploy IPv6 to sites using a service provider's IPv4 network. 6rd uses the
service provider’s own IPv6 address prefix.This limits the operational domain of 6rd to the service provider’s network
and is under direct control of the service provider.The IPv6 service provided is equivalent to native IPv6.The 6rd
mechanism relies upon an algorithmic mapping between the IPv6 and IPv4 addresses that are assigned for use
within the service provider’s network.This mapping allows for automatic determination of IPv4 tunnel endpoints from
IPv6 prefixes, allowing stateless operation of 6rd.
With a 6rd tunnel configuration, the router follows the RFC5969 standard, supporting two ways to establish a 6rd
tunnel IPv6 WAN connection:
•Auto mode. In IPv6 Auto Detect mode, when the router receives option 212 from the DHCPv4 option, auto
detect selects the IPv6 as 6rd tunnel setting.The router uses the 6rd option information to establish the 6rd
connection.
•Manual mode. Select 6rd Tunnel. If the router receives option 212, the fields are automatically completed.
Otherwise, you must enter the 6rd settings.
To set up an IPv6 6rd Internet connection:
1.Launch a web browser from a computer or WiFi device that is connected to the network.
2.Enter http://www.routerlogin.net.
A login window opens.
3.Enter the router user name and password.
The user name is admin.The default password is password.The user name and password are case-sensitive.
The BASIC Home page displays.
4.Select ADVANCED > Advanced Setup > IPv6.

							5.From the Internet Connection Type menu, select 6rd Tunnel.
The page adjusts.The router automactially detects the information in the following sections:
•6rd (IPv6 Rapid Development) Configuration.The router detects the service provider’s IPv4 network and
attempts to establish an IPv6 6rd tunnel connection. If the IPv4 network returns 6rd parameters to the router,
the page adjusts to display the correct settings in this section.
•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.
•MTU size (in bytes).The normal MTU (maximum transmit unit) value for most Ethernet networks is 1500
bytes, or 1492 bytes for PPPoE connections. Change the MTU only if you are sure that it is necessary for
your ISP connection. For more information about changing the MTU size, see Change the MTU Size on page
43.
6.Select an IPv6 Domain Name Server (DNS) Address radio button:
•Get Automatically from ISP.Your ISP uses DHCP to assign your DNS servers.Your ISP automatically
assigns this address.
•Use These DNS Servers. 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.Select an IP Address Assignment radio button:
•Use DHCP Server.This method passes more information to LAN devices but some IPv6 systems might not
support the DHCPv6 client function.
•Auto Config.This is the default setting.
This setting specifies how the router assigns IPv6 addresses to the devices on your home network (the LAN).
8.(Optional) Select the Use This Interface ID check box and specify the interface ID that you want to be used for
the IPv6 address of the router’s LAN interface.

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.
The best MTU setting for NETGEAR equipment is often the default value. In some situations, changing the value
fixes one problem but causes another. Leave the MTU unchanged unless one of these situations occurs:
•You experience problems connecting to your ISP or other Internet service, and the technical support of either
the ISP or NETGEAR recommends changing the MTU setting.These web-based applications might require an
MTU change:
•A secure website that does not open, or displays only part of a web page
•Yahoo email
•MSN portal
•America Online’s DSL service
•You use VPN and experience severe performance problems.
•You used a program to optimize MTU for performance reasons and now you are experiencing connectivity or
performance problems.
An incorrect MTU setting can cause Internet communication problems. For example, you
might not be able to access certain websites, frames within websites, secure login pages, or
FTP or POP servers.
Note
To change the MTU size:
1.Launch a web browser from a computer or WiFi device that is connected to the network.
2.Enter http://www.routerlogin.net.
A login window opens.
3.Enter the router user name and password.
The user name is admin.The default password is password.The user name and password are case-sensitive.

5.In the MTU Size field, enter a value from 64 to 1500.
6.Click the Apply button.
Your settings are saved.
If you suspect an MTU problem, a common solution is to change the MTU to 1400. If you are willing to experiment, you
can gradually reduce the MTU from the maximum value of 1500 until the problem goes away.The following table
describes common MTU sizes and applications.
