How to forward ports in my configuration?

Question

Computer networks

Initial data:

TP-Link MR 3420 router with custom firmware ROOter Project
The E3372 modem with HiLink firmware (Yota SIM card) is plugged into the router The router interface hangs

on 192.168.1.1, all local connections in the range 192.168.
192.168.8.1 (DMZ disabled, firewall disabled)
There is some other garbage at 192.168.8.100

spoiler

The Home Assistant smart home server is running on the local network at 192.168.1.200 . The control panel is available on port :8123

A domain has been set up in the duckdns service, and the DDNS support component has been installed and enabled in HA.

Requires access to Home Assistant from outside.

Ports 80 and 443 are forwarded in the router control panel

I try to open my address (let's say ha.duckdns.org) but it doesn't open.

What is done wrong or what is still missing?

Answer 1

And you definitely have a direct external address at the modem - usually mobile operators take a decent amount of money for this.
