Connect Automatically, as Required

Normally, this option should be enabled, so that an Internet connection will be made automatically,
whenever Internet-bound traffic is detected. If this causes high connection costs, you can disable
this setting.
If disabled, you must connect manually, using the sub-screen accessed from the "Connection
Status" button on the Status screen.
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 wireless ADSL modem 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 wireless ADSL modem 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 wireless ADSL modem router is shipped preconfigured to use private IP addresses on the
LAN side, and to act as a DHCP server. The wireless ADSL modem router's default LAN IP
configuration is:
