Ensure Firewall is active
IPtables is an application that allows a system administrator to configure the IPv4 tables, chains and rules provided by the Linux kernel firewall. ufw was developed to ease IPtables firewall configuration.
IPtables provides extra protection for the Linux system by limiting communications in and out of the box to specific IPv4 addresses and ports. Ubuntu provides UFW to ease firewall configuration.
# ufw enable
Ensure that any needed ports, such as ssh access, are configured properly first.
