Configuring DHCP on an interface
If you configure an interface to use DHCP, the FortiGate unit automatically broadcasts a
DHCP request. The interface is configured with the IP address and any DNS server
addresses and default gateway address that the DHCP server provides.
By default, low-end models are configured to DHCP addressing mode with Override
Internal DNS and Retrieve default Gateway from DHCP server both enabled. These
settings allow for easy out-of-the-box configuration.
To configure DHCP on an interface
1 Go to System > Network > Interface.
2 Select Create New or select the Edit icon of an existing interface.
3 In the Addressing mode section, select DHCP.
