How to Set Up a Firewall on Your VPS (UFW)

A firewall is an essential part of VPS security. Here’s how to set up UFW (Uncomplicated Firewall) to protect your server:

  1. Install UFW: sudo apt install ufw
  2. Allow SSH connections: sudo ufw allow ssh
  3. Allow other needed ports (like HTTP and HTTPS): sudo ufw allow 80,443/tcp
  4. Enable UFW: sudo ufw enable
  5. Check status: sudo ufw status

With UFW enabled, your VPS will have a basic but strong firewall in place.
