Purely out of curiosity, what are you using so much memory for? Do you do cad work or something?

Cloudflare tunnels is a great way to expose services on your network to the web.

You run a program in your server, it makes a tunnel, then you configure it on the website to visit the internal link in your network, eg

If you’re hosting a web server at home, you could have something like:

www.mydomain.net > http://192.168.1.55:8080/

You can also have cloudflare protect access to that website with email verification, google / Microsoft accounts etc.

It’s a lot to learn, but it’s very handy once you get the hang of it.

Here’s a YouTube video on the basics: https://youtu.be/Q5dG8g4-Sx0?is=J7KvNZoyjsEq33fO
