Schedule.

By default, the connection will always be active. However, you can

configure scheduler rules in order to define time segments during which the
connection may be active. Once a scheduler rule(s) is defined, this field
changes to a combo-box, allowing you to choose between the available rules.

Network.

Select whether the parameters you are configuring relate to a WAN,

LAN or DMZ connection, by selecting the connection type from the combo-box.

Physical Address.

The physical address of the network card used for your net-

work. Some cards allow you to change this address.

MTU.

MTU is the Maximum Transmission Unit. It specifies the largest packet

gateway selects the best MTU for your Internet connection. Select "Automatic
by DHCP" to have the DHCP determine the MTU. In case you select "Manual", it
is recommended to enter a value in the 1200 to 1500 range.
