I’m trying to open a port for transmission but before I get to know either of the 2 options I’d like to know what you recommend and why.
OS is xubuntu 24.04

if you use docker, docker ignores ufw rules

Thx for the correction
It’ll also ignore the default firewalld rules. IIRC it uses the
internalzone insteadGood to know, thx
I like firewalld. Its also used on many enterprise distros (RHEL, SLES).
But if you just have to open one port for something, just use what’s installed on your distro.
How often are you going to be managing ports?
Just use any tool you like, all they do is fiddle with the Kernel’s filter table.
I use UFW personally but firewalld professionally. UFW ships with Debian based and firewalld with RHEL.
If suppose I might like UFW’s syntax a bit more.
The documentation is there for everyone to see. You can easily figure out what it takes to accomplish your task with both. Honestly though, why not just try it for yourself and come to your own conclusion. If you’re on Ubuntu, UFW is probably already installed.
Firewalld had, at least last time I checked, way more capabilities than UFW. Both are fine at being basic firewalls, but I don’t think you can build a router using just UFW.
Firewalld allows some pretty advanced rules. I use it to redirect a bunch of web requests going to a certain address over a local ssh tunnel.
I was responding to OP who doesn’t seem to know much about firewalls or networking. OP is on Ubuntu which probably has UFW installed by default.
Building out Linux routers using nftables, iptables or Firewalld is a completely different topic.

Ubuntu defaults to ufw. That, by itself, justifies the use of ufw in your case.
IMO firewalld because it’s going to be more portable knowledge.
Network Filter Tables (NFT) is the current system. https://wiki.nftables.org/wiki-nftables/index.php/Main_Page
I found firewalld had so many options that it was a bit overwhelming at first, especially understanding how zones were actually meant to be used, and how each zone had a default handover for the unhandled traffic. But OpenSUSE has a GUI for it so I was able to make sense of it. UFW seemed pretty user friendly and atraight forward.
I like iptables + opensnitch
Iptables. Because in the end its iptables, so I learned it from the beginning „the right way“ and i am therefore not locked into one or another

This is even better than my answer.
