Service
On low-end FortiGate units, a DHCP server is configured, by default on the Internal interface:
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 |
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.
Alternatively, after the FortiGate unit assigns an address, you can go to System > Monitor > DHCP Monitor, locate the particular user. Select the check box for the user and select Add to Reserved.
