If you want to provide services on the server, the enterprise-class Linux distributions, such as CentOS or RHEL, contain built-in powerful firewalls, and their default firewall rules are very stringent. Therefore, if you install any custom services (such as Web servers, NFS, and Samba), their traffic is likely to be blocked by firewall rules. So you need to open
