Self-Hosting in Malaysia: Overcoming CGNAT for Your Homelab

With CGNAT, you are sharing a pool of public IPs with other subscribers. So even with DDNS setup, incoming connections will not be forwarded to you. You need to get a dedicated public IP address.

I am a MAXIS Fiber subscriber, MAXIS is using CGNAT. Setting up DDNS alone is not enough. In this article I mentioned additionally paying RM 10.00 monthly for allocating public IP. That allocated (dynamic) public IP will be dedicated to me and not shared with other subscribers. Then I setup DDNS to point (sub)domain names to this public IP.

Btw, I am not sure if all Malaysia ISP use CGNAT. Based on my experience, TM and MAXIS are both using CGNAT.

Hi Hong,

Your guide on beating CGNAT for a Malaysian homelab is genuinely useful, especially the RM 10 public IP tip. After someone requests that public IP from their ISP, they usually want to confirm it actually changed. I run whatsmyiplive.com , a free tool that shows the current public IP with no signup. It could be a small addition right after the public IP allocation step. Thanks for the clear writeup.
