====== Firewall ======

The firewall is already configured by DigitalOcean in my choice of droplet (Ubuntu 20.04 with WordPress). However if other services are to be added (in my case yes) the [[https://ubuntu.com/server/docs/security-firewall|Ubuntu firewall]] needs to be configured. See below for some extra documentation links I referred to:

  * HowTo Geek: [[https://www.howtogeek.com/115116/how-to-configure-ubuntus-built-in-firewall|How to Configure Ubuntu’s Built-In Firewall]]
  * Ubuntu Documentation: [[https://ubuntu.com/server/docs/security-firewall|Ubuntu firewall]]

===== Sample Commands =====
View current configuration:
<code bash>
ufw status
