Hi all,

I am new to this list and fairly new to Arch Linux. My Question is do I need to install a firewall? if so which one?

Thanks in advance,

For a home computer you don't need to have a firewall installed, since you're probably not running any services (e.g.: web, database or e-mail server) that would listen on certain ports. Your router most likely uses NAT [1] as well, and this means that incoming traffic won't reach any machines inside the local network, unless you've configured port forwarding [2]. ---- [1] http://en.wikipedia.org/wiki/Network_address_translation [2] http://en.wikipedia.org/wiki/Port_forwarding
