My home and code server now has 2 TB of SSD storage and 16 GB of RAM. While I’ll be using the storage for backups, etc., I’m not quite sure what I can use the 16 GB of RAM for yet. What else can I run besides Home Assistant, AdGuard Home, Drone and Tailscale? I still have my VPS running my websites,…

Weirdly enough, the name Tailscale caught my eye and I decided to investigate what it is. I checked their website and it seems that they use Wireguard to do the kind of configuration I explained some time ago. I’m curious: besides the easyness of use, what other advantages do you see on using Tailscale over a manually configured Wireguard network?

Wireguard VPN to Network Behind a CGNAT

I recently moved from the place where I was staying at to my own studio. In addition, since I was building a computer, I wanted to be able to access remotely to its capabitities, as well as any other device I have at home. Thus, I thought: let’s set up a VPN!

The problem arised when I went to the configuration of my router and saw that my WAN IP was in the format 172.xxx.xxx.xxx. I immediately knew that that was a private IP. On my ignorance, I decided to search why I didn’t have an actual public IP.


Well… I moved recently and was thinking about setting up a VPN with my new fancy router. But I discovered something: the ISP put me behind a giant NAT. Didn’t even know that Carrier Grade NATs were a thing and it never happened to me back in Portugal. Suggestions? I want a simple way to access the network remotely: just for the machines, not for the Internet.
