Using DDNS and Port Forwarding to achieve remote access to devices on an internal network

Introduction

• Recently, I got into an AI drawing software called stable-diffusion-webui. Due to its heavy reliance on GPU, I could only use my home computer for this purpose (which has a 6-year-old GTX 1060😥). However, as I work remotely, I decided to explore the realm of Dynamic Domain Name System (DDNS) to achieve remote control of my home computer and other network devices.
