CentOS 7 comes with firewalld by default. So disable firewalld because VestaCP uses IPtables & with Fail2ban. Here Firewall - Iptables Intrusion Detection - Fail2ban # systemctl stop firewalld.service # systemctl disable firewalld.service Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service. Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service. # systemctl mask firewalld.service Created symlink from /etc/systemd/system/firewalld.service to /dev/null. Reboot your server so that all updates can take affect and then check your Firewalld Status. # reboot # systemctl status firewalld
