Disable Port Scan And Dos Protection; Respond To Ping On Internet Wan Port; Mtu Size; Configuring Lan Ip Settings - NETGEAR MBR814X Reference Manual

If you have an "Always on" connection, this setting has no effect.

Disable Port Scan and DOS Protection

The Firewall protects your LAN against Port Scans and Denial of Service (DOS) attacks. This
should be disabled only in special circumstances.

Respond to Ping on Internet WAN Port

If you want the router to respond to a 'ping' from the Internet, select the 'Respond to Ping on
Internet WAN Port' check box. This should only be used as a diagnostic tool, since it allows your
router to be discovered. Do not select this box unless you have a specific reason to do so.

MTU Size

The normal MTU (Maximum Transmit Unit) value for most Ethernet networks is 1500 Bytes, or
1492 Bytes for PPPoE connections. For some ISPs you may need to reduce the MTU. But this is
rarely required, and should not be done unless you are sure it is necessary for your ISP connection.

Configuring LAN IP Settings

The LAN IP Setup menu allows configuration of LAN IP services such as DHCP and RIP. These
features can be found under the Advanced heading in the main menu of the browser interface.
The router is shipped preconfigured to use private IP addresses on the LAN side, and to act as a
DHCP server. The router's default LAN IP configuration is:
• LAN IP addresses—192.168.0.1
• Subnet mask—255.255.255.0
