Network Addressing Requirements

Before you can begin installation, you must know how your computer gets an IP address. Your Internet Service Provider (ISP) or corporate network administrator can give you this information. Use the same method to connect the Firebox to the Internet that you use for your computer. For example, if you connect your computer directly to the Internet with a broadband connection, you can put the Firebox between your computer and the Internet and use the network configuration from your computer to configure the Firebox external interface.

You can use a static IP address, DHCP, or PPPoE to configure the Firebox external interface. For more information about network addressing, see Configure an External Interface.

Your computer must have a web browser. You use the web browser to configure and manage the Firebox. Your computer must have an IP address on the same network as the Firebox.

In the factory default configuration, the Firebox assigns your computer an IP address with DHCP (Dynamic Host Configuration Protocol). You can set your computer to use DHCP and then you can connect to the device to manage it. You can also give your computer a static IP address that is on the same network as the trusted IP address of the Firebox. For more information, see Enable Your Computer to Connect to Fireware Web UI.
