(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.
If you do not specify an ID here, the router generates one automatically from its MAC
address.
12. Select an IPv6 Filtering radio button:
•
Secured. In secured mode, which is the default mode, the router inspects both
TCP and UDP packets.
•
Open. In open mode, the router inspects UDP packets only.
13. Click the Apply button.
Your settings are saved.
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
•
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.
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.
