Heights Telecom - Port forwarding issues | Port 80/443 Conflict

🤯 The Mystery of the Missing Port Forward: Fixing the BeFibre (Heights Telecom) HT-6766BE Router

If you host web apps and use a fibre service with the Heights Telecom HT-6766BE or simular router, you’ve probably run into a frustrating issue: you cannot forward the standard HTTP (80) or HTTPS (443) ports to your internal server. Your web server is configured correctly, but traffic just isn't getting through. Here’s why and the crucial setting you need to change.

🛑 The Problem: Router Management Steals Your Ports

Unlike most consumer routers, the Heights Telecom HT-6766BE doesn't just listen on a high port (like 8080) for its management interface. The firmware is configured by the ISP to use a separate feature called Net Service Settings to control which ports the router uses for its own remote management.

By default, these Net Service ports are set to:

• HTTP (Web Interface): Port 8080

• HTTPS (Secure Web Interface): Port 48443

This is usually done to keep the standard ports 80 and 443 free for the customer's use. The problem is, if you need to use ports 80/443, you need to tell the router not to use its default 8080/48443 either!

🔑 The Solution: The Net Service Hand-Off

The router’s Port Forwarding feature only works correctly if the management interface is not actively listening on the ports you are trying to forward.

To successfully forward ports 80 and 443 to your web application server, you must explicitly tell the router’s management interface to step aside.

Step-by-Step Configuration

1. Log in to the Web Interface: Access your router via a browser (the default is usually http://192.168.40.1).

2. Locate Net Service Settings: Click Advanced in the bottom right, Click Security, and then click Net Service on the left menu.

3. Change the Ports: You will find fields for the WAN (Wide Area Network/Internet side) configuration of HTTP and HTTPS services.

   • Change the default 8080 to 80. Also tick the box to the left of the port.

   • Change the default 48443 to 443. Also tick the box to the left of the port.

4. Save: Apply the changes.

5. Configure Port Forwarding: Now, go to your standard Port Forwarding and create the rules:

   • Rule 1 (HTTP): Forward External Port 80 to Internal IP (Your Server) on Internal Port 80.

   • Rule 2 (HTTPS): Forward External Port 443 to Internal IP (Your Server) on Internal Port 443.

Once this is done, the router should properly hand off external traffic on ports 80/443 to your server.

⚠️ The Catch: The Reverting Settings

You may find this fix only lasts for a few days (4–7 days is common) before your ports suddenly stop working again! This is the infamous TR-069 issue, and it's covered in the next post.
