what's better to manage ports? ufw or firewalld?
what's better to manage ports? ufw or firewalld?
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
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.
OS is xubuntu 24.04
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.
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.
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
