N150 and N300 WiFi DSL Modem Routers
If your ISP did not provide a service name, leave this field blank.
Note: The default setting of the Connection Mode menu is Always On to provide a steady IPv6 connection. The modem router never terminates the connection. If the connection is terminated, for example, when the modem is turned off, the modem router attempts to reestablish the connection immediately after the PPPoE connection becomes available again.
10.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 DHCv6 client function. This is the default setting.
•Auto Config. The modem router automatically configures its IPv6 address based on the IPv6 protocol.
11.(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 modem router’s LAN interface.
If you do not specify an ID here, the modem router generates one automatically from its MAC address.
12.(Optional) Change the NAT filtering mode:
•Secured. In secured mode, the modem router inspects both TCP and UDP packets.
•Open. In open mode, the modem router inspects UDP packets only. This is the default mode.
13.Click the Apply button. Your settings are saved.
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.
