How to Block Websites Using VPN

In todays digital landscape, controlling online access is more important than everwhether youre managing screen time for children, enforcing productivity in a workplace, or safeguarding sensitive networks from malicious content. While traditional methods like browser extensions or host file edits offer basic website blocking, they are often circumvented by tech-savvy users or easily disabled. This is where Virtual Private Networks (VPNs) come into playnot just as tools for privacy and geo-spoofing, but as powerful, enterprise-grade mechanisms for website restriction and content filtering.

Contrary to popular belief, VPNs are not solely designed to bypass restrictionsthey can also be configured to enforce them. By routing traffic through a controlled server environment, a properly configured VPN can block access to specific domains, categories of content, or even entire regions of the internet. This tutorial will guide you through the technical and strategic process of blocking websites using a VPN, covering setup procedures, best practices, real-world applications, and recommended tools.

Understanding how to leverage a VPN for website blocking empowers individuals, educators, IT administrators, and parents to create safer, more focused digital environments. Unlike simple filters, a VPN-based approach ensures enforcement at the network level, making it far more resilient to tampering or bypass attempts. This guide will equip you with the knowledge to implement such controls effectively and securely.

Step-by-Step Guide

Step 1: Understand How VPNs Work for Content Filtering

Before configuring a VPN to block websites, its essential to grasp the underlying mechanics. A VPN creates an encrypted tunnel between your device and a remote server. All internet trafficweb browsing, app data, streamingflows through this tunnel. The server then forwards requests to their destinations and relays responses back.

When used for website blocking, the VPN server acts as a gateway with built-in filtering rules. Instead of allowing all outbound requests, the server inspects domain names or IP addresses and denies access to those listed in a blocklist. This happens before the request reaches the public internet, making it impossible for the client device to bypass the restriction without disconnecting from the VPN.

Key distinction: Not all VPNs support content filtering. Consumer-grade free or basic VPNs typically focus on anonymity and speed, not control. To block websites, you need a VPN service that offers administrative controlsoften found in business, enterprise, or managed VPN solutions.

Step 2: Choose a VPN with Website Blocking Capabilities

Not every VPN provider allows you to define custom blocklists or apply content filters. When selecting a solution, look for the following features:

• Admin dashboard A web-based interface to manage users, devices, and filtering rules.
• Custom domain blocklists Ability to input specific URLs or domains to block.
• Category-based filtering Predefined categories like social media, gaming, adult content, or gambling.
• Device grouping Assign different rules to different users or devices.
• Logging and reporting Visibility into attempted access and blocked requests.

Popular enterprise-grade VPNs with robust filtering include:

• OpenVPN Access Server Open-source, self-hosted solution with full control over access policies.
• Palo Alto Networks GlobalProtect Enterprise firewall-integrated VPN with advanced content filtering.
• Fortinet FortiClient Offers secure remote access with URL filtering and application control.
• ExpressVPN for Teams Includes content filtering options for business users.
• NetGuard (Android) / Little Snitch (macOS) Though not traditional VPNs, these network firewalls can be paired with VPNs for granular control.

For personal or small-scale use, consider a self-hosted OpenVPN server on a Raspberry Pi or cloud VPS. This gives you complete authority over what gets blocked and how.

Step 3: Set Up a Self-Hosted OpenVPN Server (Advanced Option)

If you prefer full control and dont want to rely on third-party services, setting up your own OpenVPN server is a cost-effective and highly secure method.

Requirements:

• A Linux-based server (Ubuntu 22.04 LTS recommended)
• Root or sudo access
• A static public IP address or dynamic DNS service
• Basic command-line familiarity

Installation Steps:

1. Update the system: Run sudo apt update && sudo apt upgrade -y
2. Install OpenVPN and Easy-RSA: Run sudo apt install openvpn easy-rsa -y
3. Copy Easy-RSA files: Run make-cadir ~/easy-rsa
4. Generate certificates and keys: Navigate to ~/easy-rsa and run ./easyrsa init-pki, then ./easyrsa build-ca, followed by ./easyrsa build-server-full server nopass and ./easyrsa gen-dh
5. Generate a TLS key: Run openvpn --genkey --secret ta.key
6. Configure the server: Copy the sample config: cp /usr/share/doc/openvpn/examples/sample-config-files/server.conf.gz /etc/openvpn/, then decompress with gzip -d /etc/openvpn/server.conf.gz
7. Edit server.conf: Use nano /etc/openvpn/server.conf and ensure these lines are set:
   • push "redirect-gateway def1" Forces all traffic through the VPN
   • push "dhcp-option DNS 8.8.8.8" Uses Google DNS (or your preferred resolver)
   • Enable client-to-client if needed

8. Enable IP forwarding: Edit /etc/sysctl.conf and uncomment net.ipv4.ip_forward=1. Then run sudo sysctl -p
9. Configure firewall (UFW): Allow OpenVPN traffic: sudo ufw allow 1194/udp and enable NAT: sudo ufw default allow routed
10. Start and enable OpenVPN: Run sudo systemctl start openvpn-server@server and sudo systemctl enable openvpn-server@server

Step 4: Implement Website Blocking via DNS Filtering

Once your OpenVPN server is running, the next step is to block websites. The most effective and scalable method is DNS-level filtering.

By default, your OpenVPN server pushes Google DNS (8.8.8.8) to clients. Replace this with a filtering DNS resolver such as:

• Pi-hole Open-source network-wide ad and domain blocker
• NextDNS Cloud-based filtering with customizable blocklists
• AdGuard Home Self-hosted DNS sinkhole with categories

For this guide, well use Pi-hole as the filtering engine.

Install Pi-hole on the Same Server:

1. SSH into your server and run: curl -sSL https://install.pi-hole.net | bash
2. Follow the installer prompts. When asked for DNS upstream providers, choose Custom and enter 127.0.0.1

   5335

   (Pi-holes local resolver).
3. After installation, access the Pi-hole web interface via http://your-server-ip/admin

Add Blocklists:

In the Pi-hole dashboard, navigate to Group Management > Blacklist. Here, you can manually enter domains to block:

• facebook.com
• twitter.com
• instagram.com
• youtube.com
• netflix.com

For bulk blocking, paste entire blocklists from trusted sources:

• Steven Blacks Unified Hosts
• AdAway
• Polish Filters

Click Update Lists to apply. Pi-hole will now intercept DNS requests from all connected devices and return a null response for blocked domains.

Configure OpenVPN to Use Pi-hole DNS:

Edit your OpenVPN server configuration (/etc/openvpn/server.conf) and replace:

push "dhcp-option DNS 8.8.8.8"

with:

push "dhcp-option DNS 10.8.0.1"

(Assuming Pi-hole runs on the same server at 10.8.0.1the default OpenVPN subnet.)

Restart OpenVPN: sudo systemctl restart openvpn-server@server

Now, every device connecting to your VPN will use Pi-hole as its DNS resolverblocking all listed websites at the network level.

Step 5: Deploy Client Configurations

Generate client configuration files for each device:

1. In your ~/easy-rsa directory, run: ./easyrsa build-client-full client1 nopass
2. Generate the client config: cp /usr/share/doc/openvpn/examples/sample-config-files/client.conf ~/client1.ovpn
3. Edit client1.ovpn to include:
   • remote your-server-ip 1194 udp
   • ca ca.crt
   • cert client1.crt
   • key client1.key
   • tls-auth ta.key 1
   • auth SHA256
   • cipher AES-256-CBC

4. Copy the files (ca.crt, client1.crt, client1.key, ta.key, and client1.ovpn) to the client device.
5. Import the .ovpn file into any OpenVPN client (OpenVPN Connect, Tunnelblick, etc.).

Once connected, the clients traffic is routed through your server, DNS queries are filtered by Pi-hole, and blocked websites are inaccessibleeven if the user attempts to change DNS settings on their device.

Step 6: Test and Validate Blocking

After setup, test the configuration:

• Connect a device to the VPN.
• Attempt to visit a blocked site (e.g., youtube.com).
• Verify the page fails to load or displays a blocked message from Pi-hole.
• Check the Pi-hole dashboard for a logged DNS query with status blocked.
• Disconnect from the VPN and attempt to access the same siteensure it loads normally.

This confirms the blocking is enforced only via the VPN and cannot be bypassed while connected.

Best Practices

Use Category-Based Filtering for Scalability

Manually listing hundreds of websites is unsustainable. Instead, leverage pre-built category filters:

• Block all Social Media domains
• Block Gambling, Pornography, Proxy/Anonymizer
• Allow Educational, Productivity, News

Tools like Pi-hole and NextDNS offer hundreds of pre-defined categories. You can enable or disable them with a single toggle, making management far more efficient.

Segment Users and Devices

Not all users need the same restrictions. Use group policies to apply different rules:

• Childrens devices: Block social media, gaming, streaming
• Work laptops: Block entertainment sites during business hours
• Guest devices: Allow unrestricted access

OpenVPN Access Server and enterprise solutions allow you to assign users to groups with individual filtering profiles. For self-hosted setups, you can create multiple client configs with different DNS settings.

Enforce HTTPS and DNS Encryption

Blocking HTTP sites is easy. But many users now use encrypted DNS (DoH/DoT) or HTTPS proxies to bypass filters. To counter this:

• Use DNS over TLS (DoT) or DNS over HTTPS (DoH) only through your controlled resolver (Pi-hole or NextDNS)
• Block outbound traffic to public DoH providers like Cloudflare (1.1.1.1) or Google (8.8.8.8) using firewall rules
• On your server, use iptables to block DNS queries to external resolvers:

  sudo iptables -A OUTPUT -p udp --dport 53 ! -d 10.8.0.1 -j DROP
  sudo iptables -A OUTPUT -p tcp --dport 53 ! -d 10.8.0.1 -j DROP

This ensures all DNS traffic must go through your filtering server.

Log and Monitor Activity

Visibility is critical. Enable logging in Pi-hole and export reports weekly. Monitor:

• Top blocked domains
• Frequency of bypass attempts
• Devices making the most requests

This data helps refine your blocklists and identify policy violations.

Regularly Update Blocklists

New domains emerge daily. Schedule weekly updates:

• Run pihole -g to refresh Pi-hole blocklists
• Subscribe to community-maintained blocklist feeds
• Remove false positives (e.g., legitimate sites accidentally blocked)

Use tools like blocklist.site to test if a domain is truly malicious or just flagged.

Combine with Time-Based Rules

For productivity or parental control, apply time-based restrictions:

• Block gaming sites only between 8 AM4 PM on weekdays
• Allow streaming during weekends

Pi-hole doesnt natively support time-based rules, but you can use cron jobs to toggle blocklists:

0 8 * * 1-5 /usr/bin/pihole -b facebook.com twitter.com
0 17 * * 1-5 /usr/bin/pihole -w facebook.com twitter.com

This adds the sites to the blocklist at 8 AM and removes them at 5 PM on weekdays.

Real Examples

Example 1: Parental Control in a Household

A family uses a Raspberry Pi running OpenVPN and Pi-hole to enforce screen time limits. The parents configure the server to block:

• YouTube, TikTok, Instagram, and Netflix during school nights (6 PM8 AM)
• Online gaming sites (Roblox, Steam, Xbox Live) on weekdays
• Adult content and gambling sites at all times

Each childs tablet and phone connects to the familys VPN automatically via Wi-Fi profile. The parents receive weekly reports showing attempted access to blocked sites. When a child tries to access YouTube during school hours, the request is silently dropped. The child sees This site is blocked, with no option to override it. On weekends, the blocklist is temporarily disabled via a cron job, allowing unrestricted access.

Example 2: Corporate Productivity Policy

A mid-sized tech company deploys FortiClient with Cloudflare Gateway to enforce a no social media during work hours policy. All employees must connect to the corporate VPN to access internal tools. The IT team configures:

• Block: Facebook, Twitter, Reddit, Twitch, Discord (except for approved teams)
• Allow: LinkedIn, Slack, Google Workspace
• Log all access attempts

Employees attempting to visit blocked sites while connected to the VPN receive a Policy Violation page. The system generates monthly reports showing usage trends. One employee repeatedly tried to bypass the filter using a mobile hotspot. The IT team detected this via IP logs and retrained the employee on acceptable use policy. No further violations occurred.

Example 3: School Network Security

A high school uses OpenVPN Access Server to provide secure remote access for students. The schools filtering policy blocks:

• All adult content (CIPA compliance)
• Online gambling and betting sites
• Proxy and VPN services (to prevent circumvention)
• Peer-to-peer file sharing domains

Students cannot access these sites even if they use their personal devices at home. The schools network administrator uses NextDNS to apply category filters and receives alerts when students attempt to access restricted content. This approach reduces disciplinary incidents and ensures compliance with federal education laws.

Example 4: Digital Detox for Remote Workers

A freelance designer sets up a personal VPN on a cloud VPS to help reduce distractions. She configures Pi-hole to block:

• News websites (CNN, BBC, The Guardian)
• YouTube and streaming platforms
• Reddit and Hacker News

She connects to the VPN only during her focused work blocks (9 AM12 PM and 2 PM5 PM). Outside those hours, she disconnects and enjoys unrestricted browsing. This method is far more effective than browser extensions, which she could disable with a single click. The VPN ensures the block is always active when she needs it.

FAQs

Can I block websites using any VPN?

No. Most consumer VPNs (like NordVPN or ExpressVPN for individual users) do not allow you to define custom blocklists. You need a business-grade or self-hosted VPN with administrative controls.

Will blocking websites via VPN slow down my internet?

There may be a slight latency increase due to encryption and routing through a remote server. However, with a well-configured server and fast internet, the difference is negligibletypically under 50ms. Using a nearby server location minimizes impact.

Can users bypass website blocking on a VPN?

If the VPN is properly configured with DNS filtering and firewall rules, bypassing is extremely difficult. Users cannot change DNS settings while connected, and attempts to use DoH/DoT are blocked at the network level. The only way to bypass is to disconnect from the VPN.

Is it legal to block websites using a VPN?

Yes, as long as you own the network or device and are not violating any laws (e.g., blocking access to legal content in a workplace without notice). In homes, schools, and businesses, content filtering is widely accepted and often required by policy or regulation.

Do I need to install software on every device?

Yes. Each device must have the VPN client installed and configured to connect to your server. However, once configured, the blocking is automatic and persistent.

Can I block apps (not just websites) using a VPN?

VPNs primarily filter based on domain names or IP addresses. To block apps like Instagram or WhatsApp, you must block their associated domains (e.g., instagram.com, whatsapp.net). For granular app-level control, combine your VPN with device management tools like Mobile Device Management (MDM) or parental control software.

What happens if the VPN server goes down?

If the server fails, devices will lose connectivity. To avoid disruption, use a redundant server or failover DNS. For critical environments, consider a secondary filtering method like local firewall rules.

How do I unblock a website I accidentally blocked?

Access your filtering tools dashboard (Pi-hole, NextDNS, etc.), navigate to the blacklist, and remove the domain. Then refresh the DNS cache (e.g., run pihole -g or restart the service). The site will be accessible the next time a client connects.

Can I use this method to block ads too?

Yes. Many blocklists used for website filtering also include ad-serving domains. Pi-hole and AdGuard Home are specifically designed to block ads, trackers, and malware domainsmaking them excellent dual-purpose tools.

Is a VPN better than browser extensions for blocking websites?

Yes. Browser extensions can be disabled, uninstalled, or bypassed. A VPN enforces blocking at the network level, making it device-agnostic and tamper-proof. It works across all apps and browsers, not just Chrome or Firefox.

Conclusion

Blocking websites using a VPN is not a workaroundits a robust, enterprise-grade solution for digital control and content management. Unlike browser extensions or host file edits, a properly configured VPN ensures that restrictions are enforced at the network level, making them nearly impossible to circumvent. Whether youre a parent seeking to protect your children, an IT administrator enforcing workplace policies, or an individual striving for digital focus, leveraging a VPN for website blocking offers unmatched reliability and scalability.

This guide has walked you through the technical foundations, from selecting the right tools to deploying self-hosted solutions with DNS filtering. Youve seen how real-world users apply these techniques to improve productivity, safety, and compliance. The key takeaway: control begins with infrastructure. By routing all traffic through a filtered gateway, you shift from reactive, user-dependent restrictions to proactive, system-enforced policies.

Start smallinstall Pi-hole on a Raspberry Pi and connect one device. Observe the results. Gradually expand your blocklists, add user groups, and refine your rules. Over time, youll build a secure, intelligent network that adapts to your needs without constant oversight.

Remember: technology should empower, not entrap. The goal of website blocking isnt to restrict freedom, but to create space for focus, safety, and intentionality. With the right tools and thoughtful implementation, a VPN becomes more than a privacy toolit becomes a digital sanctuary.
