VPS Firewall – What Do You Need to Know?
If you’ve recently purchased a VPS or are considering one, you might have questions about securing it. A VPS firewall is a critical tool for protecting your server from unauthorized access and potential threats. This guide will explain everything you need to know about VPS firewalls, including how they work, why they’re important, and how to manage them effectively.
What is a VPS Firewall?
A VPS firewall is a security system that monitors and controls incoming and outgoing network traffic based on predefined rules. It acts as a barrier between your server and the internet, allowing only authorized traffic to pass through while blocking potential threats.
Firewalls can be hardware-based, software-based, or a combination of both. For VPS hosting, software firewalls are commonly used because they are easy to configure and manage.
A VPS firewall is essential for several reasons:
Why Do You Need a VPS Firewall?
A VPS firewall is essential for several reasons:
Enhanced Security
A firewall protects your server from hackers, malware, and other cyber threats. It blocks unauthorized access attempts and prevents malicious traffic from reaching your server.
Performance
By filtering out unwanted traffic, a firewall reduces the load on your server. This improves performance and ensures your website runs smoothly.
Compliance
Many industries require firewalls to meet security standards and regulations. Using a firewall helps you stay compliant and avoid legal issues.
Without a firewall, your VPS is vulnerable to attacks, which can lead to data loss, downtime, or even financial damage.
How Does a VPS Firewall Work?
A VPS firewall works by analyzing network traffic and applying predefined rules. Here’s how it functions:
Traffic Analysis:
The firewall examines incoming and outgoing data packets.
Rule Application:
It checks the packets against a set of rules to determine if they should be allowed or blocked.
Action:
Based on the rules, the firewall either permits or denies the traffic.
For example, if you have a rule to allow traffic on port 80 (HTTP), the firewall will let web requests through. If a hacker tries to access a restricted port, the firewall will block the attempt.
Where to Find Your Firewall Policies
To manage your VPS firewall, you need to access your firewall policies. Here’s how you can find them:
- Log in to your Progressive Robot account.
- Navigate to the Control Panel.
- Click on ‘Virtual Private Servers’.

- Status: Shows if the policy is active, disabled, being configured, or removed.
- Port(s): Lists the ports enabled for incoming traffic.
Click on a policy to view more information, such as:
- Action: Specifies if traffic is allowed.

- Created On: The date the policy was created.
- Assigned IP: The IP addresses the policy applies to.

Tips for Managing Your VPS Firewall
Managing a VPS firewall requires attention to detail and regular maintenance. Here are some tips to help you:
1. Regularly Review Rules
Ensure your firewall rules are up-to-date and relevant. Remove outdated rules and add new ones as needed.
2. Limit Access
Only allow traffic from trusted IP addresses. This reduces the risk of unauthorized access.
3. Use Strong Protocols
Prefer secure protocols like SSH (port 22) or HTTPS (port 443). Avoid using insecure protocols like FTP.
4. Monitor Logs
Check firewall logs regularly for suspicious activity. This helps you identify and address potential threats.
5. Test Changes
After updating rules, test your server to ensure everything works as expected. This prevents accidental downtime.
6. Enable Default Deny
Set your firewall to deny all traffic by default and only allow specific traffic. This is a safer approach than allowing all traffic by default.
