What are Firewalls?

A Firewall is a set of rules that allow or deny inbound or outbound traffic based on the ports. This allows you to manage the restrictions for inbound and outbound traffic based on the ports your applications and server requires. These firewalls are deny-by-exception, meaing they deny all except the ports you want to allow.

A Firewall is a separate entity and is not attached to any servers by default. Once you have creted a firewall and updated the rules accordingly, then you will need to go the servers you wish to add the Firewall to and attache the firewal to them.
