-Most consumer-grade internet connections are hidden behind CG-NAT and are not reachable from the internet. This is done to save IP addresses, as IPv4 has a limited range. If you have a static public IPv4 or any IPv6 address, you won’t need the setup from this tutorial.

 There are already services like [localtunnel](https://github.com/localtunnel/localtunnel) or [ngrok](https://github.com/ngrok) for this purpose, but when you actually start using them, you will often find out that they have limitations on their free plans. So, we will configure our own custom setup once and have it always available for convenient and practical usage which will save a lot of time and nerves in the long run.

 ## Introduction
 
-In the previous article, I wrote about a temporary SSH tunneling technique to bypass CG-NAT. This method is not suitable for exposing permanent services, at least not without `autossh` manager. Proper tools for this are [rapiz1/rathole](https://github.com/rapiz1/rathole) or [fatedier/frp](https://github.com/fatedier/frp). I chose Rathole since it's written in Rust and offers better performance and benchmarks.

 ## Conclusion
 
-Most consumer-grade internet connections are behind a CG-NAT. This setup allows you to bypass CG-NAT and host an unlimited number of websites from your home almost for free. You can use it for web servers in virtual machines, LXC containers, SBC computers, etc. - anywhere you can run Docker.

 It is simple, cheap, and you can set it up in 30 minutes. Like anything, it also has some downsides, one of them is the overhead latency caused by an additional network hop between the VPS and your home network, but it's a reasonable tradeoff.
