[SOLVED] How do I enable firewall in a fresh install of Arch?

Hi. I've just installed Arch.

The Arch Wiki says: "Arch Linux comes with two options for managing a firewall, neither of which is enabled automatically."

Now how do I enable the firewall?

Read through the following links...caveat, it's a bit of a tedious process to get a firewall setup under Arch. I considered giving up on Arch when I first encountered all of the steps that are required to get a firewall setup.

iptables

Simple stateful firewall

Uncomplicated Firewall

Or you skip the legacy iptables and check the nftables wiki page .

install nftables, issue 2 simple commands and basic firewall protection works.

Setting up a basic firewall is simple.

If using iptables

sudo pacman -S ufw
sudo ufw enable
sudo systemctl enable ufw.service

If using nftables

sudo pacman -S firewalld
sudo systemctl enable --now firewalld

This is a very simple, outbound ok inbound blocked type of setup.

Adding a 3rd package is not what I call simple.

Simple firewall

nftables comes with a simple and secure firewall configuration stored in the /etc/nftables.conf file.

The nftables.service will load rules from that file when started or enabled.
