Firewall

Introduction

A firewall is a security product that filters out malicious traffic. Traditionally, firewalls have run in between a trusted internal network and an untrusted network – e.g., between a private network and the Internet.

With E2E Network Firewall, you can define firewall rules that provide fine-grained control over network traffic. Network Firewall works together with E2E Firewall Manager so you can build policies based on Network Firewall rules and then centrally apply those policies across your virtual private clouds (VPC) and accounts.

E2E Firewalls Features

• Multi-Platform Support

  • Integrates with Iptables (Linux), Firewalld (Linux), and Windows Firewall, supporting a wide range of operating systems.
  • Compatible with multiple network configurations, including virtual private clouds (VPC).

• Granular Firewall Rule Configuration

  • Enables the creation of detailed firewall rules for precise control over network traffic.
  • Provides the ability to open or close ports on Iptables, Firewalld, and Windows Firewall.

• Centralized Management via E2E Firewall Manager

  • Allows for centralized policy creation and deployment across multiple VPCs and accounts.
  • Simplifies the process of applying and managing firewall policies across your infrastructure.

• Comprehensive Firewall Management Actions

  • Users can access the console, power off, reboot, reinstall, lock, and delete the firewall with ease.
  • Provides full control over the firewall's operational settings and management.

• Protection from Malicious Traffic

  • Filters out harmful traffic, preventing unauthorized access to the network.
  • Secure against common network attacks by enforcing strict firewall rules.

• VPC Integration

  • Allows users to associate the firewall with multiple networks and attach VPCs, providing flexibility and scalability in network security management.

• Automatic FortiFlex Licensing

  • FortiGate-VM licenses are provisioned, activated, and released automatically — no manual license key entry required.
  • License state is kept in sync with VM state: paused on Power Off, reactivated on Power On, released on Delete.

Key Benefits of using E2E Firewall

• Enhanced Security

  • Ensures comprehensive protection by blocking malicious traffic and unauthorized connections.
  • Minimizes the risk of cyberattacks, reducing vulnerabilities across systems.

• Centralized Policy Management

  • Simplifies network security management with E2E Firewall Manager for creating, applying, and modifying firewall rules from a single console.
  • Reduces administrative overhead and improves operational efficiency by allowing administrators to manage multiple firewalls from one location.

• Fine-Grained Network Control

  • Gives administrators full control over the network by allowing them to open or close ports selectively, ensuring only necessary services are accessible.
  • Customizable firewall rules offer the flexibility to fine-tune security protocols based on network needs.

• Scalability and Flexibility

  • Adapts to growing networks by enabling easy integration with multiple VPCs and networks, ideal for both small and large-scale environments.
  • Supports businesses that need scalable, flexible, and secure firewall solutions for dynamic infrastructures.

• Operational Control and Flexibility

  • Immediate access to firewall management actions, such as rebooting or reinstalling, empowers administrators to respond quickly to changing network conditions or security incidents.
  • The ability to lock or delete the firewall ensures that administrators can maintain tight control over access and configuration.

• Secure Use in Public Networks

  • Windows Firewall offers additional protection when using public networks by blocking unsolicited connection attempts, safeguarding against potential threats when connecting to untrusted networks.

Licensing

E2E Networks FortiGate Firewall uses FortiFlex dynamic licensing — a Fortinet-managed system that automatically provisions and manages your FortiGate-VM license throughout its lifecycle. You do not need to enter any license key manually.

Action	What happens to the license
Create Firewall	License is automatically provisioned and activated on the VM
Power Off	License is paused — Fortinet stops billing for the license
Power On	License is automatically reactivated
Reinstall	A fresh license token is automatically re-injected into the VM
Delete	License is automatically released — no manual steps needed

For a full explanation of how FortiFlex licensing works, see FortiGate Licensing — FortiFlex.

Firewall Detail

Click on any firewall in the list to open its detail page. The detail page shows all the configuration saved at the time of creation, including the firewall name, plan, and status.
