How to configure DHCP relay on FortiGate FW (Photos)

How to Configure DHCP Relay on FortiGate FW (Photos)?

  • DHCP (Dynamic Host Configuration Protocol) is a network protocol used to automatically assign IP addresses and other settings to devices on a network.

  • As networks grow, it becomes increasingly difficult to manage and configure each device manually. To address this problem, most companies use DHCP Relay instead of including a DHCP server on every subnet. By enabling DHCP relay, one DHCP server can support multiple subnets and simplify the configuration process. This helps reduce administrative overhead and allows for more efficient management of IP addresses across the network.

On windows Server 2022, install DHCP service

Fortunately, this article will provide you with the steps necessary to get your VM Trial license working properly. We will discuss the necessary steps for activating and validating your FortiGate VM Trial license as well as troubleshooting any issues that may arise during the process.

Understanding the FortiGate VM Trial License Limitations

Before troubleshooting, it’s crucial to understand the limitations of the evaluation license. The FortiGate Trial license does not support HTTPS for management, which means that you would have to manage it via HTTP.

Moreover, when the Fortigate default login is used, which is the admin, no password is required. After pressing enter, the firewall system forces you to set up a new password for better security.

Diagnosis: Identifying the VM License Issue

Often, the problem begins with your FortiGate VM trial license not working as expected.

To troubleshoot this, enter #execute factoryreset then type y. This action is aimed at restoring the factory settings and fixing the VM license issue.

Setting up the initial configuration of a FortiGate Firewall.

To show the current IP address and the mode

#get system interface physical

IP_DHCP

Configuring Network Settings

Next step: switch your network configuration to static and enter the IP address manually. Use the commands below to achieve this:

#config system interface

#show

To edit (configure) certain port number

#edit port1

#set mode static

#set ip 192.168.0.135 255.255.255.0

To access the firewall through that port, you must enable HTTP (included with the evaluation license). Upgrading to the full version will give you the added benefit of accessing the firewall via HTTPS and SSH as well.

The command for this is:

#set allowaccess http ssh ping https

change IP to static
mode:static
allowaccess

Setting up Internet Access and DNS Serve

By default, the system utilizes Fortinet’s DNS servers. However, you have the flexibility to modify the DNS settings if required.

You need to set up a static default route to get an internet access route.

Network > Static Routes

By default, Fortinet’s DNS servers are being used, but you can alter the DNS settings if desired.

You can launch a new console window from the graphical user interface (GUI).

Concluding thoughts

Finally, it is important to note that a new console window can be launched from the graphical user interface (GUI) for more convenience.

In the end, while the FortiGate VM Trial license has its limitations, understanding and working around these constraints can allow you to explore the robust benefits of FortiGate VM and eventually make an informed decision about upgrading to the full version.
