From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
Rules
- Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.
- No misinformation
- No NSFW content
- No hate speech, bigotry, etc

This is not great advise to say the least. You want to block all incoming but allow all outgoing.
Also visiting a https site will not magically ports. It uses 443/tcp and if you are using a site with WebRTC (used for calls on platforms like teams) ports 443/UDP and 50000-65535/UDP. However, there is no reason you need to know that unless you are in a professional field
