Flint 3 OpenWrt Router Setup Guide for KPN FTTH

Introduction

This guide provides a complete setup for the GL.iNet Flint 3 router with OpenWrt to work with KPN FTTH internet and IPTV services. The Flint 3 is a compact, powerful router that offers excellent performance and flexibility for advanced networking configurations.

This setup will configure:

• VLAN 6 for PPPoE Internet connection
• VLAN 4 for KPN IPTV (multicast) services
• IGMP proxy for multicast TV streaming
• AdGuard Home for DNS filtering and security

The configuration uses the default IP range of 192.168.8.x and provides both wired and wireless IPTV options.

Note: In earlier attempts there was a dedicated port (LAN4 / port 7) for IPTV, but now it's working over all the LAN ports same as the default KPN ExperiaBox.

Quick Start

1. Prerequisites - Check requirements and prepare your setup
2. Initial Router Setup - Basic router configuration and SSH access
3. Network Configuration - Core network and VLAN setup
4. Advanced Configuration - Technical details and explanations
5. AdGuard Home Setup - DNS filtering and ad blocking
6. IPTV Setup - IPTV configuration and testing

Optional: 7. Access Point Setup - Extend Wi-Fi coverage with a second Flint 3

What You'll Get

After completing this setup, you'll have:

✅ Working internet connection via PPPoE on VLAN 6 ✅ Proper VLAN configuration for all ports ✅ AdGuard Home DNS filtering and security ✅ IGMP proxy for multicast TV streaming ✅ IPTV working on all LAN ports ✅ Complete firewall and DHCP configuration
