Which firewall is best for Linux ? Does anyone offer free firewall for Linux ? Have you guys tried it ? How was the experience ?
Two well known Procedures i know. after built in linux firewall like iptable rules.
one is fail2ban you can install it with ssh command apt-get install fail2ban and the second one is ufw and you can install it with apt-get install ufw.
both are easy to use. you can get there tutorial easily from internet. also command lines to install and make iptable rules. as a custom rules.
Firewall isn't really needed if you have a linux vm/container unless you are really new to these stuff, I mean everyone can secure his VPS against most of the attacks. And no, there's no free Firewall available AFAIK.
I was using APF and it works fine but you need to configure it basing what you have on vps.
I heard Iptables is a secure one. Its really a nice and simple frontend to Netfilter and a powerful firewall manager built on top of iptables.
iptables I think is mostly used firewall for linux distros, and it's easy to configure base on your needs.

you can use shorewall to manage ip tables as well.It is also known as “Shoreline Firewall”. It is built upon the iptables/ipchains netfilter system.
