By defaut, the Firewall is inatcive and hence the Apache web server can be accessed from outside.
$ sudo ufw status
Status: inactive
If the firewall is actived. You must instruct your firewall to allow Apache web service to be accessible.
We can first list the ufw application profiles by:
$ sudo ufw app list
Available applications:
Apache
Apache Full
Apache Secure
OpenSSH
Then allow 'Apache Full'
$ sudo ufw allow 'Apache Full'
Now you should see:
$ sudo ufw status
Status: active
To Action From
-- ------ ----
Apache Full ALLOW Anywhere
OpenSSH ALLOW Anywhere
Apache Full (v6) ALLOW Anywhere (v6)
OpenSSH (v6) ALLOW Anywhere (v6)
