Managing Firmware with the FortiGate BIOS : Loading firmware : Configuring TFTP parameters
 
Configuring TFTP parameters
Starting from the main BIOS menu
[C]: Configure TFTP parameters.
Selecting the VLAN (if VLANs are used)
[V]: Set local VLAN ID.
Choose port and whether to use DHCP
[P]: Set firmware download port.
The options listed depend on the FortiGate model. Choose the network interface through which the TFTP server can be reached. For example:
[0]: Any of port 1 - 7
[1]: WAN1
[2]: WAN2
Enter image download port number [WAN1]:
[D]: Set DHCP mode.
Please select DHCP setting
[1]: Enable DHCP
[2]: Disable DHCP
If there is a DHCP server on the network, select [1]. This simplifies configuration. Otherwise, select [2].
Non-DHCP steps
[I]: Set local IP address.
Enter local IP address [192.168.1.188]:
This is a temporary IP address for the FortiGate unit network interface. Use a unique address on the same subnet to which the network interface connects.
[S]: Set local subnet mask.
Enter local subnet mask [255.255.252.0]:
[G]: Set local gateway.
 
The local gateway IP address is needed if the TFTP server is on a different subnet than the one to which the FortiGate unit is connected.
TFTP and filename
[T]: Set remote TFTP server IP address.
Enter remote TFTP server IP address [192.168.1.145]:
[F]: Set firmware file name.
Enter firmware file name [image.out]:
Enter [Q] to return to the main menu.
