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.

Is there a downside to sticking to iptables over ufw? (sh.itjust.works)

In short, sell me on ufw.

I learned recently that yfw is basically replacing iptables "everywhere", and as I'm getting old and crusty, this means that I have to learn something new when I'd much rather practice yelling at kids to get off my lawn.

To me, iptables is fine, and I like its flexibility. I've been using it ever since it de facto replaced ipchains, so ease of use isn'treally a factor in this equation.

So my more pointed question is: Can I just stick to iptables, or am I missing out on something that can only be done with ufw?

These days it's a frontend for nftables. iptables is a legacy system that's eventually going to be removed (just like ipchains before it).

On modern systems, iptables is a wrapper around nftables. So you're essentially using nftables except without the ability to use any of its more powerful features.

I was about to say the same -- and also: nftables syntax is a lot cleaner compared to iptables, and the whole configuration can be loaded from a single file just like pf, without doing the dump/reload cycle that iptables required. Unless UFW does features like defining zones which a user might need (like firewalld), then it's not a huge improvement on bare nftables usability-wise.
