To keep your VPS safe from viruses, DDoS attacks, and illegal access, it is essential to secure it. Configuring firewall rules is one of the best methods to improve server security. Incoming and outgoing traffic is managed by a firewall, which blocks malicious or superfluous requests while permitting only trusted connections.<\/p>\n

This tutorial will show you how to use UFW (Uncomplicated Firewall), a simple program included on the majority of Linux distributions, to set up firewall rules on a VPS.<\/p>\n

Let us follow the guide:<\/strong><\/p>\n

    \n
  1. Check UFW Status:
    \nFirst, verify if UFW is installed and running:<\/p>\n
    sudo ufw status<\/pre>\n
    If UFW is inactive, you\u2019ll see \u201cStatus: inactive.\u201d<\/li>\n
  2. Enable UFW:
    \nEnable UFW to start managing firewall rules:<\/p>\n
    sudo ufw enable<\/pre>\n<\/li>\n
  3. Allow SSH Connections:
    \nTo prevent locking yourself out, allow SSH (default port 22):<\/p>\n
    sudo ufw allow 22\/tcp<\/pre>\n
    If your SSH runs on a custom port, replace 22 with that port number.<\/li>\n
  4. Allow Essential Services:
    \nAllow HTTP (80) and HTTPS (443) traffic for web servers:<\/p>\n
    sudo ufw allow 80\/tcp\r\nsudo ufw allow 443\/tcp<\/pre>\n<\/li>\n
  5. Deny Unnecessary Ports:
    \nBlock all other ports that are not in use. For example, to deny port 21 (FTP):<\/p>\n
    sudo ufw deny 21\/tcp<\/pre>\n<\/li>\n
  6. Enable Logging (Optional)
    \nEnable logging to monitor firewall activity:<\/p>\n
    sudo ufw logging on<\/pre>\n<\/li>\n
  7. Verify Rules:
    \nCheck the list of active rules:<\/p>\n
    sudo ufw status verbose<\/pre>\n<\/li>\n<\/ol>\n
