Welcome to our guide on how to install and configure Endian Firewall on VirtualBox. Endian Firewall Community (EFW) is an open-source Red Har Enterprise Linux (RHEL) based security software offering a stateful packet firewall, basic web and email security, open-source antivirus and powerful VPN (IPsec and SSL).

Install and Configure Endian Firewall on VirtualBox

This guide focuses on the installation and configuration of the open-source version of Endian Firewall on VirtualBox.

Download Endian Firewall Community

Navigate to the Endian Firewall community downloads page and grab the latest installation ISO.

Create New Virtual Machine

Once you have the Endian Firewall ISO downloaded, launch VirtualBox and create a new virtual machine. In this guide, we are going to setup EFW with the following minimum requirements;

  • 20GB storage disk
  • 2GB RAM
  • 2 CPU cores
  • At least two network interface cards. This guide uses 4 interfaces (LAN, WAN, DMZ, WiFi). (Arrangement may vary for your case)
    • First Interface: GREEN Zone (LAN) – Internal network- intnet
    • Second Interface: RED Zone (WAN) – Bridged
    • Third Interface: ORANGE Zone (DMZ) – Internal network- intnet1
    • Fourth Interface: BLUE Zone (WiFi) – Internal network- intnet2

Once you have created a new virtual machine, mount the Endian Firewall ISO and boot the new virtual machine with it.

Next, you need to configure Endian Firewall GREEN interface IP. GREEN interface IP is the LAN interface IP for EFW. You can learn more about network zones on the network settings page. The default IP for the GREEN interface is 192.168.0.15/24. Be sure to change this based on your network.

Remember this is the internal network interface we assigned while setting up virtual machine.
