Acknowledgement: Written by Google Gemini, edited by jmac

This page provides one specific example of accessing an Apache web server running on a remote machine. In this specific case color Apache is running on a Linux virtual machine hosted on Google Cloud Platform (GCP).

1. Find External IP Address

curl -4 ifconfig.me

2. Allow HTTP Traffic in GCP Firewall

Edit the VM instance in the Google Cloud Console. Scroll down to the Firewalls section and check the box for Allow HTTP traffic.

3. Allow HTTP Traffic in VM Firewall (UFW)

sudo ufw allow 'Apache'

4. Verify Apache Service

sudo systemctl status apache2

5. Access Default Page

Open your browser and visit:

http://<YOUR_EXTERNAL_IP>

Note: not https:// since the default Apache installation does not include SSL/TLS configuration.
