Proxy & VPN Blocker

აღწერა

Proxy & VPN Blocker In Brief

Using the proxycheck.io API this plugin will prevent Proxies, Tor, VPN’s, IP Addresses, Ranges or ASN’s & select Countries from accessing your WordPress Login, Registration pages, Select Pages and Posts (or the whole site!), and also prevent them from making comments on your pages and posts. This will also help to prevent spammers as many of them use Proxies to hide their true location.

Main Blocking Features

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

  • Block Proxies, SOCKS4/4a & SOCKS5/5h, The Onion Router (TOR), Web Proxies and Compromised Servers.
  • Optionally block VPN’s.
  • Support for Cloudflare.
  • Both IPv4 and IPv6 supported.
  • TLS Support for secure communication with the proxycheck.io API.
  • Block select Countries and/or Continents by selecting them in a list – optionally make this list a whitelist instead.
  • Caching of known good IP addresses for half an hour (configurable between ten and 240 minutes) after the first check to save on repeat queries (and slowing down good visitors).
  • Optional blocking based on IP Risk Score functionality provided by the proxycheck.io API.

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 even on a specific Div class.

Added Extras

Proxy & VPN Blocker has gone much further than just providing the basic API features of proxycheck.io. It has country blocking baked right in, an API Key statistics page and proxycheck.io Whitelist and Blacklist manipulation right from your WordPress Dashboard for ease of use, providing the Dashboard API is enabled on your proxycheck.io account. This is so you can manage most things from within WordPress and don’t have to log in to proxycheck.io.

Customisation

  • You can specify a list of pages and posts to protect in addition to what is protected by default.
  • You can select a specific page on your site as the Blocked page rather than the default message page.
  • You can specify the blocked message shown if a custom Block page isn’t specified.
  • You can specify a custom tag text that will be shown instead of the url the query was made from, in your positive detection log.

The proxycheck.io API

This plugin can be used without a proxycheck.io API key, however it would be limited to 100 daily queries. You can get a free API key from proxycheck.io that allows for 1000 free daily queries, ideal for small WordPress sites!

There are paid higher query options available, Please see below how the free and paid API options work.

  • 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.

You are not limited to using your API key on one site or application.

User IP Logging Feature

Proxy & VPN Blocker now has the ability to log User’s Registration IP Address locally, with display of the IP Address next to each user in the Users list in admin and on User profile pages (viewable by Administrators). The Plugin will also log the most recent login IP address for each user, this is also displayed in the User’s list and profile page (viewable by Administrators). These IP’s are displayed as a link to the proxycheck.io Threats page for the IP Address.

Caching Plugin Notice

If your WordPress site is using a caching plugin (WP Rocket, WP Super Cache etc) Blocking on specific pages, posts or the option to block on all pages may not function due to how caching plugins work.

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

This plugin is not made by proxycheck.io despite being recommended by the company, if you need support with the Proxy & VPN Blocker plugin please use the WordPress Support page for this plugin and not proxycheck.io support on their website, unless you have a query relating to the proxycheck.io API, service or your account. Likewise the plugin developer does not provide support for issues relating to your proxycheck.io account or the API. The plugin developer and proxycheck.io are not the same entity.

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.

It works perfectly at startup. Then it starts generating the 502 error: 502 Bad Gateway. Is there any solution for this?
11.05.2021
I'm running a large classifieds site and the plugin helps me block a boatload of unwanted traffic and users. We had a lot of scammers before that were uing VPNs and proxies and this plugin solved that problem completely.
04.01.2021
Does what it's supposed to do and blocks most of what I want it to block (proxies and VPN), the rest is blocked by other anti-spam measures. An issue we had was quickly resolved (we hit the 1000 free api calls when there was increased spammer/hacker activity and all logins were blocked). The new option that sends an e-mail at 90% of our API allowance now alerts us in time and the plugin stops blocking when API calls are exhausted. 5 stars!

  • Check implemented to disable the Country Whitelist option if the country list is empty, this is to avoid a situation where nobody can access the website.
  • Fixed a redirection issue when adding/removing IP’s on the Blacklist Editor page in Settings, it functioned, but redirected you back to the Whitelist Editor page instead of the Blacklist Editor Page after form submission.
  • Added an experimental Debugging Information Option (perhaps expandable in future) which enables a Debugging Page in PVB Settings displaying some information that may be useful for the PVB developer to help diagnose issues.
  • Significantly decreased the amount of Icon font files included in Settings so that only the used icons are included as their own font.

1.8.1 2021-02-11

  • Multiple fixes for issues affecting the use of known good IP cache. This did not affect the detection of Proxies and VPN’s and only stopped known good IP’s being cached to prevent constant recheck.
  • Refactored API Call function.

1.8.0 2021-02-09

  • The Settings UI has been broken down into tabs due to the amount of options available now. The page length was deemed to be too long and confusing for some users.
  • The settings UI has been refreshed, they are now also in Dark Mode depending on OS/Browser setting if supported.

1.6.3 2020-05-03

  • Further refinements to “Block on Entire Site”.

1.6.2 2020-05-03
