Which UFW service to use for Apache2?

Hi, @joestroup

This really depends from your needs. There are three profiles available for Apache:

• Apache: This profile opens only port 80 (normal, unencrypted web traffic)
• Apache Full: This profile opens both port 80 (normal, unencrypted web traffic) and port 443 (TLS/SSL encrypted traffic)
• Apache Secure: This profile opens only port 443 (TLS/SSL encrypted traffic)

It is recommended that you enable the most restrictive profile that will still allow the traffic you’ve configured. Since we haven’t configured SSL for our server yet in this guide, we will only need to allow traffic on port 80:

sudo ufw allow 'Apache'

You can verify the change by typing:

sudo ufw status

The output will provide a list of allowed HTTP traffic:

Output
Status: active

To                         Action      From
--                         ------      ----
OpenSSH                    ALLOW       Anywhere                  
Apache                     ALLOW       Anywhere                
OpenSSH (v6)               ALLOW       Anywhere (v6)             
Apache (v6)                ALLOW       Anywhere (v6)

As indicated by the output, the profile has been activated to allow access to the Apache web server.

Hope that this helps! Regards, Alex
