Configuring DHCP services
Go to System > DHCP > Service to configure DHCP services. On each FortiGate
interface, you can configure a DHCP relay and add DHCP servers as needed.
On FortiGate models 50 and 60, a DHCP server is configured, by default, on the
Internal interface, as follows:
IP Range 192.168.1.110 to 192.168.1.210
Netmask 255.255.255.0
Default gateway 192.168.1.99
Lease time 7 days
DNS Server 1 192.168.1.99
You can disable or change this default DHCP Server configuration.
These settings are appropriate for the default Internal interface IP address of
192.168.1.99. If you change this address to a different network, you need to
change the DHCP server settings to match.
