Proxy & VPN Blocker

Description

Proxy & VPN Blocker

Proxy & VPN Blocker prevents access to your WordPress login, registration pages, selected pages and posts (or the entire site!) by proxies, Tor, VPNs, specific IP addresses, ranges, ASN, and selected countries using the proxycheck.io API. It also blocks comments from these sources, helping to prevent spam as many spammers use anonymising services to hide their true location.

Main Features

Below is a list of the main features supported by this Plugin.

  • Detects and Blocks Proxies, SOCKS4/4a & SOCKS5/5h, The Onion Router (TOR), Mysterium Network Nodes, Web Proxies, Compromised Servers and more, to your specifications.
  • Optional blocking of VPNs.
  • Support for Cloudflare or other Content Delivery Network providers headers.
  • Support for both IPv4 and IPv6.
  • Securely communicates with the proxycheck.io API.
  • Block select Countries (Geolocation) by selecting them from a list, with the option to create a whitelist instead.
  • Caching of known good IP addresses for a configurable duration (between ten and 240 minutes) to minimize repeat queries and improve performance for legitimate visitors.
  • Optional blocking based on IP Risk Score functionality provided by the proxycheck.io API.
  • Logging of User Registration and Most Recent login IP Address right in the users list and user profile page (for admin viewing).

Note: By default blocking happens on Login, Registration, WP-Admin area, posting comments, and pingbacks, but you can extend this to blocking on any specified page or post from within the Pages/Posts lists or specifying it to be restricted access when creating a Page/Post in the WordPress editor.

Extras

Proxy & VPN Blocker goes beyond the basic API features of proxycheck.io. It includes built-in country blocking, an API Key statistics page, and allows modification of your proxycheck.io Whitelist and Blacklist directly from your WordPress Dashboard. This integration streamlines the management process by providing most functionalities within WordPress, eliminating the need to login to the proxycheck.io Dashboard.

Customization

  • Specify additional pages and posts to protect beyond the default settings.
  • Choose a specific page on your site as the «Access Denied» page displayed to blocked visitors, replacing the default message page.
  • Define a custom blocked message to be displayed if a custom Block page redirect isn’t specified.

The proxycheck.io API

This Plugin can be used without a proxycheck.io API key, but it will be limited to 100 daily queries to the API. To enhance the capabilities, you can obtain a free API key from proxycheck.io, which allows for 1,000 free daily queries, making it suitable for small WordPress sites.

Here’s an overview of the free and paid API options:

  • Free Users without an API Key: 100 Daily Queries.
  • Free Users with an API Key: 1,000 Daily Queries.
  • Paid Users with an API Key: 10,000 to 10.24 Million+ Daily Queries.

It’s important to note that your API key can be used on multiple sites or applications, providing flexibility in its usage.

User IP Logging Feature

Proxy & VPN Blocker allows for local logging of user registration IP addresses. The IP addresses are displayed next to each user in the Users list and on their profile pages, visible to administrators. The Plugin also logs the most recent login IP address for each user, which is also displayed in the User’s list and profile page, with the IP address linked to the proxycheck.io Threats page.

Caching Plugin Notice

If your WordPress site utilizes a Caching Plugin (e.g., WP Rocket, WP Super Cache), please note that blocking on specific pages, posts, or the option to block on all pages may not function correctly due to caching plugin mechanisms, a DONOTCACHEPAGE option is provided, which goes some way to solving this.

Privacy Notice

This Plugin is designed to work with the proxycheck.io API and by extension of this, the IP addresses of your site visitors are sent to the API to be checked. No other user identifiable information is transmitted. Please refer to the proxycheck.io privacy notice and GDPR Compliance for further information. The Plugin developer does not have access to information that identifies your website users.

Disclaimer

FAQ

What is proxycheck.io?

Proxycheck.io is a simple, accurate and reliable API for the detection and blocking of people using Proxies, Tor & VPN servers.

Blocking Proxies and VPN’s on all pages?

Although this Plugin has an option to block Proxies & VPN’s on all pages, this option is not generally recommended due to significantly higher query usage, but was added on user request.

It is important to note that if you are using a WordPress caching Plugin (eg WP Super Cache, WP Rocket, W3 Total Cache and many others), these will prevent the Proxy or VPN from being blocked if you are using ‹Block on all pages› as the caching Plugin will likely serve the visitor a static cached version of your website pages. As the cached pages are served by the caching Plugin in static HTML, the code for proxy detection will not run on these cached pages. This won’t affect the normal protections this Plugin provides for Log-in, Registration and commenting.

I accidently locked myself out by blocking my own country/continent, what do I do?

The fix is simple, upload a .txt file called disablepvb.txt to your wordpress root directory, PVB looks for this file when the proxy and VPN checks are made, if the file exists it will prevent the Plugin from contacting the proxycheck.io API. You will now be able to log in and remove your country/continent in the PVB Settings.

Remember: If you ever have to do this, delete the disablepvb.txt file after you are done! If you don’t remove it, the Plugin wont be protecting your site.

Blocks your WP Cron from running, seems support no longer available for this plugin either. Best off installing another one

Setup is simple but when all is said and done it does NOT block the chosen country from accessing the shop website. it however does block admin access from that country (which is not what I wanted or configured for)
