Almost all Linux distributions come without a firewall by default. To be more correct, they have an inactive firewall. Because the Linux kernel has a built-in firewall and technically all Linux distros have a firewall but it is not configured and activated.
How do I know if firewall is installed Linux?
If your firewall uses the built-in kernel firewall, then sudo iptables -n -L will list all the iptables contents. If there is no firewall the output will be mostly empty. Your VPS may have ufw already installed, so try ufw status .
Which firewall used in Linux?
Iptables
Iptables/Netfilter is the most popular command line based firewall. It is the first line of defence of a Linux server security. Many system administrators use it for fine-tuning of their servers. It filters the packets in the network stack within the kernel itself.
