General

The top part of the configuration window displays general communication parameters. It is recommended not to change the default values in this screen unless you are familiar with the networking concepts they represent. Since your gateway is configured to operate with the default values, no parameter modification is necessary. You can configure the following general connection settings:

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. To learn how to configure scheduler rules please refer to section 11.11.

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. For more information, please refer to section 5.2.

Physical Address

The physical address of the network card used for your network. Some cards allow you to change this address.

MTU

MTU is the Maximum Transmission Unit. It specifies the largest packet size permitted for Internet transmission. The default setting, Manual, allows you to enter the largest packet size that will be transmitted. The recommended size, is 1492. You should leave this value in the 1200 to 1500 range. To have the gateway select the best MTU for your Internet connection, select Automatic.
