Fortigate Command line IP address assignment

Fortigate command line IP address assigment is one of the tasks you need to perform when configuring a Fortigate device on GNS3 or if you a CLI-lover. To get your Fortigate device to comunicate with your GNS3 VM and allow you access via the GUI, you will need to first access your the device via the command line and configure your management interface with a static or dynamic address via the CLI.

The GNS3 emulation software is one of the platforms where you can practice and master your Fortinet skills. Even though the FortiOS running on the GNS3 platform is an evaluation version, it is just enough to get you started with all you need to perfect most of the skills required to configure and deploy any Fortigate model.

Fortigate Command line IP Address

The Fortigate command line IP address configuration process is a fairly straight forward process just like you have it with most router OS platforms. First, you have to go into interface configuration mode, then to the particular port you want to confgure. Once there, you can decide whether your Fortigate IP address is going to be static or dhcp. Here, we are going to go with dhcp. The steps for both options are pratically thesame. See commands below

While in the selected port mode, it would be good to verify that there is not IP address configured on the port before proceeding to assign your preferred IP address. To see the IP address on an interface, just issue the command “get” command from the port mode. See command and output below.

The output above shows that port3 has no configured IP address. I will now proceed to configure an IP on it via dhcp and define the access types. For this lab, I am going to allow ping and https. See commands below.

Verify Fortigate IP address assignment

In the interface configuration mode, in the selected port mode, type get to see the ip address and access types configured on the interface. See command and output below.

Finally, ensure that your cable connectedness is done properly, then you are good to go.

How to set IP address on an interface in Fortigate CLI?

I want to set IP address on Port1 of Fortinet Fortigate CLI.

I am trying to use the following command:

set ip 192.168.176.0 255.255.255.0

but I am getting the following error before 255.255.255.0:

IP address is illegal Value parse the error

I have tried a lot but failed to understand the reason behind this issue.

By default, all the interfaces of Fortigate are in DHCP mode. So, you need to make it static and allow access for protocols which you want to use there.

Another thing to note here is that if you are trying to assign 192.168.176.0/24 to an interface then that's an invalid IP as it is a Network address.

Try, below commands,

configure the port1 IP address and netmask.

For example:

You want to configure "192.168.176.0/24" as FortiGate interface ip-address:

  • Network ip of 192.168.176.0/24 = 192.168.176.0
  • First usable ip of 192.168.176.0/24 = 192.168.176.1
  • Last usable ip of 192.168.176.0/24 = 192.168.176.254
  • Broadcast ip of 192.168.176.0/24 = 192.168.176.255

You can't configure the network ip address as interface ip. Instead use a usable ip.
