Quick installation using DHCP

Most of the FortiGate desktop models have a default configuration that includes a DHCP server on the lan (or internal) interface and a security policy that securely allows all sessions from the internal network to reach the Internet. Because of this, you can connect your desktop FortiGate to the Internet in two simple steps:

Note that, in order to use this installation method, your ISP must provide connectivity with DHCP and accept DHCP requests without authentication. You must also use IPv4 to connect your FortiGate to the Internet.

  1. Connect the wan interface on your FortiGate to your ISP-supplied equipment, and connect the internal network to the default lan interface on your FortiGate. Turn on the ISP’s equipment, the FortiGate, and the computers on the internal network.

  2. For computers on the internal network:

    Windows Vista/7/8/10 users:

    1. Go to Network and Sharing Center and select Change adapter settings.

    2. Open the Local Area Connection (Ethernet or WiFi, whichever applies) and select Properties.

    3. Select Internet Protocol Version 4 (TCP/IPv4) and then select Properties.

    4. Select Obtain an IP address automatically and Obtain DNS server address automatically.

    5. Click OK.

    Mac OS X users:

    1. Go to System Preferences > Network and select your Ethernet connection.

    2. Set Configure IPv4 to Using DHCP.

To confirm successful Internet connectivity from any computer on the internal network, open a web browser and browse to any website.
