Hi,
I'm a long-time Linux user (two and a half decades since Slackware
7.1). I've been using RHEL clones mainly for the last ten years or so,
on desktops as well as servers (local and Internet-facing). For
firewalling I simply chose the default Firewalld.
I understand under Debian there are different possibilities to handle
firewalls. As far as I understand, ufw (Uncomplicated firewall) seems
to be the default, though Firewalld seems to be an option.
Any recommendations ?
You can use pure "iptables" and "iptables-persistent" as a third option.
It will be more efficient to learn iptables syntax and use it on any
distro than learning syntax of a different wrappers for iptables like
ufw and the others.
Develop a simple ruleset and manage it with command line utils or
directly edit the rules files with text editor.
There is also a new kid around called "nft" which should replace
iptables, but its syntax is super weird and non-intuitive for me, so I
consider it a downgrade.
Luckily iptables` syntax still supported via iptables-to-nft rules
translation with support for the most of iptables extensions, so for the
time being iptables syntax will stay available for use.
