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.
In order to use this installation method, your ISP must provide connectivity with DHCP and accept DHCP requests without authentication. You must also be using IPv4 to connect your FortiGate to the Internet.
- Connect the FortiGate's wan interface to your ISP-supplied equipment, and then connect the internal network to the FortiGate’s default lan interface. Turn on the ISP’s equipment, the FortiGate, and the PCs on the internal network.
- (Windows Vista/7/8/10 users) Go to Network and Sharing Center and select Local Area Connections. Select Properties. Select Internet Protocol Version 4 (TCP/IPv4), then select Properties. Select Obtain an IP address automatically and Obtain DNS server address automatically.
(Mac OS X users) Go to Network Preferences and select Ethernet. Set Configure IPv4 to Using DHCP.
From any PC on the internal network, open a web browser and browse to any website. You can successfully connect to the Internet.
