Set Up an IPv6 6rd Tunnel Internet Connection
6rd protocol makes it possible to deploy IPv6 to sites using a service providers 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 Tunnel Internet Connection:
1. Launch a web browser from a computer or wireless device that is connected to the 
network.
2. Enter http://www.routerlogin.net.

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 have severe performance problems.
•You used a program to optimize MTU for performance reasons and now you have 
connectivity or performance problems.
Note: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.
To change the MTU size:
1. Launch an Internet browser from a computer or wireless device that is connected to the 
network.
2. Type http://www.routerlogin.net or http://www.routerlogin.com.

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.

MTUApplication
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 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 have large email attachments, for example.
1436 Used in PPTP environments or with VPN.
