Good day, Mr.Hong, thank you for sharing this blog post, reading it has helped me plan for my homelab networking to be used outside of my local network. Regarding the ISP in Malaysia using CGNAT, i am abit confused because when i query chatgpt regarding external access to my computers, it mentioned that using DDNS would not work if the ISP is using CGNAT, but i would assume that you got it working using DDNS, would it mean that the ISP in Malaysia are not using CGNAT? Thank you for reading. Your insight in this topic would be much appreciated.
