In today’s interconnected world, managing internet access at home can feel like a game of digital whack-a-mole. You’ve set up parental controls, yet somehow, your kids still manage to bypass them using VPNs. This guide will show you how to block VPNs on your router effectively. Blocking VPNs can help maintain the integrity of your network controls, ensuring that all users adhere to the rules you’ve set. Let’s explore how we can achieve this!
Understanding VPNs and Why Block Them?
Virtual Private Networks (VPNs) are tools that encrypt internet traffic, providing privacy and security by masking users’ IP addresses. While VPNs are useful for legitimate activities like browsing safely on public Wi-Fi, they can also be used to circumvent network restrictions. For parents or network administrators, blocking VPNs is crucial to enforce content restrictions or bandwidth usage policies.
Why Focus on ForestVPN?
Among the myriad of VPN services, ForestVPN stands out for its robust security features and user-friendly interface. However, if you’re looking to prevent unauthorized VPN use on your home network, it’s essential to understand how ForestVPN operates to effectively block it.
Steps to Block VPN on Your Router
1. Access Control:
– MAC Address Filtering: Identify the MAC addresses of devices you want to restrict and block VPN access. This method is somewhat rudimentary but effective in small networks.
2. Disable VPN Passthrough:
– PPTP, L2TP, IPSec Passthrough: Navigate to your router’s security settings and disable these options to prevent VPN traffic from passing through.
3. Use DNS Filtering:
– Implement DNS Filters: Some routers, like those with Asuswrt-Merlin firmware, offer DNS filtering options. Set up filters to block VPN-related domains.
4. Firewall Rules:
– Block Common VPN Ports:
– UDP Port 500 (for IPsec)
– UDP Port 4500 (for NAT-T)
– TCP Port 1723 (for PPTP)
– Create firewall rules in your router to block these ports, as they are commonly used by VPN protocols.

FAQs on How to Block VPN Access at Home
What are VPNs and why should I block them on my home network?
VPNs, or Virtual Private Networks, create secure tunnels for internet traffic, allowing users to bypass restrictions. Blocking them helps maintain control over content access, particularly for children or users who might misuse the internet.
How can I block VPNs on my router?
To block VPNs, you can disable VPN passthrough options on your router, implement MAC address filtering, use DNS filtering like CleanBrowsing, and create firewall rules to block common VPN ports such as UDP 500 and 4500.
What is CleanBrowsing and how does it help in blocking VPNs?
CleanBrowsing is a DNS filtering service that provides family-friendly options to restrict access to malicious content, proxies, and VPNs. By configuring your router to use CleanBrowsing DNS addresses, you can effectively block VPN-related traffic.
Are there specific router settings I should look for to block VPNs?
Yes, you should look for settings related to VPN passthrough (PPTP, L2TP, IPSec) and firewall rules that allow you to block specific ports commonly used by VPN services.
Can blocking VPNs affect my work-related VPN access?
Yes, if you use a VPN for work, ensure that your configuration does not block the ports used by your work VPN. You may need to create exceptions in your firewall rules for your work-related VPN.
