Select an IP Address Assignment radio button:
•
Use DHCP Server
. The 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.
•
Auto Config
. This is the default setting.
10.
To specify the interface ID for the IPv6 address of the modem router’s LAN interface, select
the
Use This Interface ID
check box, and enter the interface ID.
If you do not specify an ID here, the modem router generates one automatically from its
MAC address.

Set Up an IPv6 6rd Tunnel 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 that is provided is equivalent to native IPv6.
The 6rd mechanism relies on 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, enabling stateless
operation of 6rd.
To set up an IPv6 6rd tunnel connection:
1.
Launch an Internet browser from a computer or WiFi device that is connected to the
network.
2.
Type
.
A login screen displays.
3.
Enter the modem router user name and password.
The user name is
admin
. The default password is
password
. The user name and
password are case-sensitive.

The modem router automatically detects the information in the
Router’s IPv6 Address
on LAN
field. This field shows the IPv6 address that is acquired for the modem 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.
7.
In the 6rd Configuration section, configure the 6rd settings:
•
6rd Prefix
. Enter the IPv6 prefix that your ISP gave you.
•
6rd Prefix Length
. Enter the IPv6 prefix length that your ISP gave you.
•
6rd Border Relay Address
. Enter the border router’s IPv4 address that your ISP
gave you.
•
6rd Address Mask Length
. Enter the IPv4 mask length that your ISP gave you.
8.
Select an IPv6 Domain Name Server (DNS) Address radio button:
•
Get Automatically from ISP
. The ISP’s DHCP server automatically assigns IPv6
DNS server addresses.
•
Use These DNS Servers
. Enter the static IPv6 (
not
IPv4) DNS server addresses that
your ISP provided to you.

Select an IP Address Assignment radio button:
•
Use DHCP Server
. The 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.

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

Table 3.
Common MTU sizes
MTU
Application
1500
The largest Ethernet packet size. This setting is typical for connections that do not use PPPoE
or VPN and is the default value for NETGEAR modem routers, adapters, and switches.
1492
Used in PPPoE environments.
1472
Maximum size to use for pinging. (Larger packets are fragmented.)
1468
Used in some DHCP environments.
1460
Usable by AOL if you do not send or receive large email attachments, for example.
1436
Used in PPTP environments or with VPN.
1400
Maximum size for AOL DSL.

Change the MTU Size
WARNING:
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. Change the
MTU only if you are sure that it is necessary for your ISP connection.
To change the MTU size:
1.
Launch an Internet browser from a computer or WiFi device that is connected to the
network.
2.
Type
.
A login screen displays.
3.
Enter the modem router user name and password.
The user name is
admin
. The default password is
password
. The user name and
password are case-sensitive.
4.
Click the
OK
button.
The BASIC Home screen displays.
5.
Select
ADVANCED > Setup > WAN Setup
.
The WAN Setup screen displays.
6.
In the
MTU Size
field, enter a value from 616 to 1500.
The normal MTU value for most Ethernet networks is 1500 bytes, 1492 bytes for PPPoE
connections, or 1436 for PPTP connections.
