This guide on how to block vpn on router will walk you through the necessary steps to block VPN usage on your router, helping you maintain the integrity and security of your network.
What is a VPN?
A Virtual Private Network (VPN) is a technology that allows users to create a secure connection over the internet, providing them with anonymity and privacy while browsing. It essentially creates a private tunnel between your device and the internet, encrypting all data transmitted through it.
VPNs are commonly used by businesses, organizations, and individuals to protect sensitive information from being intercepted or accessed by unauthorized parties. However, they can also be used for malicious purposes such as hiding illegal activities or bypassing restrictions set by networks.
Why Block VPN on Router?
Blocking VPN access on your router can serve various purposes, including:
Enforcing Usage Policies:
If you have a no-VPN policy in your organization or household, blocking VPNs at the router level ensures that all devices connected to the network comply with this rule.
Maintaining Network Security:
By blocking VPN access, you prevent potential threats from entering your network through unsecured connections.
Preventing Circumvention of Geo-Restrictions:
Some services, such as streaming platforms and online gaming networks, have regional restrictions in place. Blocking VPNs can prevent users from bypassing these restrictions and accessing content that is not available in their region.
8 Step-by-step Guidelines on How to Block Vpn on Router
Step 1: Determine your Router’s IP Address and Login Credentials
To begin, you need to know your router’s IP address and login credentials. These can usually be found on the bottom of your router or in the manual. If you cannot find them, you can contact your Internet Service Provider (ISP) for assistance.
The most commonly used IP addresses are 192.168.1.1 or 192.168.0.1. But, if your router’s IP address is different, it will be indicated in the manual or on the bottom of the device. You will also need login credentials, such as a username and password, to access your router’s settings.
Step 2: Access Your Router’s Settings
Once you have your router’s IP address and login credentials, open a web browser on a device connected to your network. Type the router’s IP address into the address bar and press Enter.
This action should take you to the router’s login page. Enter the username and password you obtained earlier to log in. If you are logging in for the first time, it’s advisable to change the default login credentials to enhance security.
After logging in, you will be directed to the router’s control panel or settings page, where you can configure various settings, including blocking VPN access.
Step 3: Locate the Firewall or Security Settings
After logging into your router’s control panel, navigate to the firewall or security settings. These settings are typically found in a section labeled “Security,” “Firewall,” or “Advanced Settings.”
The exact location and naming conventions may vary depending on your router’s model and manufacturer. If you are having difficulty locating these settings, refer to your router’s user manual or the manufacturer’s support website for specific instructions.
The firewall or security settings will allow you to customize various aspects of your network’s security, including blocking VPN traffic.
Step 4: Create a Firewall Rule
Once you have located the firewall or security settings, you will need to create a new firewall rule to block VPN traffic. Look for an option to add or create a new rule, which may be labeled as “Add New Rule,” “Create Rule,” or “Custom Rule.”
When creating the rule, you will need to specify certain parameters such as the protocol, port number, and IP address. Most VPNs use distinct port numbers and protocols for their operation, with some commonly used ports being 1194 (UDP) for OpenVPN, 4500 (UDP) for IPsec, and 1723 (TCP) for PPTP.
To block VPN traffic, set the action of the rule to “Deny” or “Block.” Enter the appropriate port numbers and protocols used by popular VPN services. Additionally, some advanced routers may allow you to block ranges of IP addresses associated with VPN servers.
After configuring these settings, save the rule and ensure it is enabled. This firewall rule will help prevent devices on your network from establishing VPN connections, ensuring compliance with your network policies.
If you’re unsure of the exact parameters to use, consult your router’s manual or support documentation for further guidance.
Step 5: Use Blacklisting/Whitelisting
In addition to creating firewall rules, you can further enhance your router’s security by using blacklisting or whitelisting methods. Blacklisting involves explicitly specifying which domains, IP addresses, or services to block, while whitelisting allows only certain trusted domains, IP addresses, or services to access your network.
To use blacklisting, navigate to the blacklist section within your router’s security or firewall settings. Here, you can input the specific IP addresses or domains associated with known VPN services that you wish to block.
This method ensures that any traffic originating from these sources is denied access to your network. Common domains and IP addresses for popular VPN providers can usually be found through a simple online search or by consulting cybersecurity resources.
However, keep in mind that this method may not be 100% effective as VPN providers may frequently change their IP addresses and domains to bypass blacklisting.
Step 6: Implement MAC Address Filtering
Another effective method to block VPN traffic on your router is by implementing MAC address filtering. Each device that connects to your network has a unique MAC (Media Access Control) address.
By configuring your router to restrict or allow certain MAC addresses, you can control which devices have the ability to connect to your network and use VPN services.
To set up MAC address filtering, navigate to the “MAC Filtering” or “MAC Address Control” section within your router’s security or advanced settings.
Here, you can add the MAC addresses of devices that you wish to allow or block. For added security, you might choose to allow only specific trusted devices to connect to your network, effectively preventing all other devices from using VPNs.
Step 7: Utilize DNS Filtering
DNS (Domain Name System) filtering is another useful method for blocking VPN access on your router. DNS filtering works by blocking connections to specific domains or IP addresses, effectively denying access to their services.
Many popular VPN providers use a limited number of servers and IPs to handle their traffic, making it easier to identify and block them using this method.
To utilize DNS filtering, navigate to the “DNS” or “Web Filter” section within your router’s security settings. Here, you can input the desired domains or IP addresses associated with known VPN services that you wish to block.
Similar to blacklisting, keep in mind that some VPN providers may frequently change their servers and IPs, rendering this method partially effective.
Step 8: Save and Enable Settings
After implementing your desired methods of blocking VPN traffic, remember to save your changes and enable the applied settings. Once enabled, these measures should prevent devices on your network from establishing connections with VPN services.
However, it’s always advisable to periodically review and update these settings as new VPN providers may emerge or existing ones may change their tactics to bypass security measures.
You can also consider using a combination of these methods for added security and effectiveness. Regularly monitoring your router’s security settings and staying up-to-date with cybersecurity trends will help ensure that your network remains protected from unauthorized VPN usage.
Additionally, educating yourself and others on the risks associated with using VPNs can greatly reduce the likelihood of their use on your network. Remember, prevention is always better than cure when it comes to securing your home or office network.
