Introduction to Fortigate: Things You Must Know

The prerequisite to mastering Fortigate is to familiarize yourself with its core functionalities and network configurations. Here are several major topics of focus in Fortigate practice labs and Fortinet NSE-4 training:

Installing and Setting Up for the First Time

Setting Up a Fortigate Firewall at Lab Environment Here’s how to get started:

• Deploy FortiGate in virtual(Functioning), standalone hardware.
• Simple configuration via web interface using Fortigate GUI.
• Set up basic network configurations, firewall rules, and user authentication.

Fortigate firewall can be accessed through:

• FortiExplorer (for USB-based installation).

Fortigate Firewalls: Networking & Security Features

Network Modes: NAT or Transparent Mode

Fortigate device works in two modes mainly:

• NAT/Route Mode – Operates as a Layer 3 device, and serves as a gateway between networks.
• Transparent Mode – Operates as a Layer 2 bridge without modifying IP addresses, enabling the transparent enforcement of security policies.

These modes are critical for setting up Fortigate in various settings.

Which is Configuring your Virtual Domains(VDOM)

Fortigate supports multiple virtual domains (VDOMs) on the same firewall to allow network administrators to separate and manage traffic. This feature is commonly found in enterprise environments where departments require a different security policy.

HA (High Availability) and Traffic Shaping

The cost of network downtime can be expensive. Fortigate devices are supported in High Availability (HA) mode, where they provide failover redundancy via multiple Fortigate devices active-passive or active-active.

Traffic shaping also plays a role in managing bandwidth distribution, and prioritizing vital applications for optimal performance.

Fortigate VPN and Secure Remote Access

Routing Challenges when Implementing IPSEC VPN and Remote Access

Now that there is increased remote work, secure VPN access is more necessary than ever. Fortigate specializes in IPSEC VPN, enabling employees to connect securely to corporate networks.

How To Configure a Fortigate VPN — FortiGate Secure VPN Setup

Set up the VPN policies and authentication types.

Create site-to-site IPSEC connections between two Fortigate firewalls.

Eliminate certificate warnings so your users' access continues uninterrupted.

The best Fortigate practice labs enable learners to implement real-world VPN configurations that are critical for developing their remote access solutions proficiency.

Fortigate labs: Un-boxing, Licensing and Configuration
