Introduction

Welcome, brave network defender! You’re about to embark on an epic quest to transform a humble PC or virtual machine into a fortress of solitude (well, network security). Endian Firewall, affectionately known as Endian UTM, is a powerful Linux-based distribution offering routing, firewalling, VPN, antivirus, and more—all wrapped in a user-friendly interface.

Why Choose Endian Firewall?

• All-in-One Security: Firewall, VPN, IPS, antivirus, web filtering—no need to juggle multiple appliances.
• Easy Management: Web-based console accessible from any modern browser.
• Open Source Core: Inspired by open source you can inspect, customize, and extend.
• Active Community: Forums and wiki filled with real-life tips (and a few memes).

System Requirements

Step 1: Downloading the ISO

1. Visit the official download page:
   https://www.endian.com/…
2. Select the UTM Community Edition (CE) suitable for your architecture.
3. Verify the checksum to ensure integrity (sha256sum or similar).

Step 2: Preparing Installation Media

You have two main choices:

• USB Flash Drive: Use dd on Linux or tools like Rufus on Windows.
• VM ISO: Directly mount the ISO in your hypervisor (VirtualBox, VMware, Proxmox, etc.).

Pro tip: Label your USB “Wizard Wand” to feel even cooler.

Step 3: Boot and Begin Installation

1. Insert the USB or ISO and boot the target machine.
2. You’ll see the Endian splash screen. Press Enter to continue.
3. Choose Install Endian UTM from the GRUB menu.

Partitioning and Filesystem

The installer uses cfdisk by default:

1. Create a primary partition for / (ext4 recommended).
2. Optionally, create a swap partition (equal to your RAM size).

Hit Write, confirm with yes, then select Quit.

Configure Base System

• Set root password (choose something memorable but secure).
• Choose your time zone and keyboard layout.

Step 4: Initial Network Configuration

Endian refers to networks as red (external), green (internal LAN), and optional orange (DMZ) or blue (Wi-Fi). At minimum, configure:

• Red Interface: DHCP or static public IP.
• Green Interface: Static private IP (e.g., 192.168.1.1).

Step 5: Reboot and Access the Web Console

1. Once installation completes, remove media and reboot.
2. From any PC on the green network, open a browser to https://192.168.1.1 (adjust if you used a different IP).
3. Log in with admin/admin (you’ll be forced to change the password).

Step 6: First-Time Setup Wizard

The setup wizard helps you:

• Confirm network settings.
• Set DNS servers (Google: 8.8.8.8, Cloudflare: 1.1.1.1).
• Update the system to the latest packages (click #x21bb Update).

Step 7: Defining Firewall Rules

Endian uses zones. A simple “Green to Red” rule allows your LAN to reach the Internet:

• Navigate to Firewall gt Rules.
• Check default rules: Green-gtRed is usually allowed.
• Add custom rules: e.g., block TCP 23 (Telnet) from Green.

Step 8: Enabling VPN

Remote access is crucial. Endian supports OpenVPN and IPSec:

1. Go to VPN tab.
2. Enable OpenVPN server.
3. Download the .ovpn profile and import on your client.

Warning: Don’t share your client profile on social media—hackers are always watching!

Step 9: Web Filtering and Antivirus

Protect users from malicious sites and files:

• Web Filter: Blacklist/whitelist categories like “Adult,” “Gambling,” etc.
• Antivirus: Enable ClamAV scanning for HTTP and SMTP traffic.

Step 10: Monitoring and Logging

You’re the guardian now. Keep an eye on logs:

• Dashboard: Real-time graphs of bandwidth, connections, CPU/RAM usage.
• Logs: Firewall, VPN, Mail, Web Filter – filter by severity or source IP.

Troubleshooting Tips

• No Internet? Check gateway/DNS under Network gt Interfaces.
• VPN Won’t Connect? Verify port forwarding on upstream router (default UDP 1194).
• Updates Fail? Ensure the UTM can resolve DNS and reaches updates.endian.com.

Advanced Topics

• High Availability with CARP on two UTM appliances.
• Integrate with LDAP/AD for single-sign-on.
• Deploy IPv6 zones alongside IPv4.
