the FortiGate unit, you must reconnect to the web-based manager using the new
interface IP address.
Configuring an interface for DHCP
You can configure any FortiGate interface to use DHCP.
If you configure the interface to use DHCP, the FortiGate unit automatically broadcasts
a DHCP request. You can disable connect to server if you are configuring the
FortiGate unit offline and you do not want the FortiGate unit to send the DHCP
request.
By default, the FortiGate unit also retrieves a default gateway IP address and DNS
server IP addresses from the DHCP server. You can disable the option Retrieve
default gateway and DNS from server if you do not want the DHCP server to configure
these FortiGate settings.
