IP Restrictions with Reverse Proxy

IP restrictions allow you to limit inbound connections from a limited IP address, and to minimize unwanted traffic. Know more about the features and benefits of limiting access.

IP Restriction Reverse Proxy

What is IP Restriction in Reverse Proxy?


Several requests are being sent to web servers on a continuous basis, and also there are countless reasons to keep web services protected. With IP restrictions, we can handle the requests that come to the server. IP restrictions monitor network traffic and, if it suspects a request originating from a particular IP address is suspicious, it will either block that IP address from accessing your web service or warn you to limit access to that IP address.

IP Restrictions allows you to give selective access to web servers based on the client’s IP address. The reverse proxy product sits right in front of the backend service. Thus, protecting it from direct access by clients spread throughout the world. When The IP restrictions is enabled, it allows the users to enter specific IP addresses that they want to either allow or restrict from accessing their server using the proxy link.



How does IP Restriction work at the client end?


Let’s begin, how this IP restrictions would work in a scenario where a client of the user, who has enabled IP Restrictions feature, wants to access the user’s server:

  1. The client sends a request to the proxy link of the user’s server.
  2. The IP address of the client making the request to the proxy link is fetched.
  3. This IP address is compared with the list of IP addresses that the user has permitted or denied access to the proxy link.
  4. If the IP address is allowed for that proxy link, the client will be able to access it; else, the client would be shown a ‘403 Forbidden’ error message.


Use-Case Scenario: User wanting to allow specific IP addresses



    Let’s take the example of one of our clients belonging to an institute. He wanted to limit the access of the institute’s servers to authorized users only. As the client wanted to allow only authorized personnel to access the server, their IP addresses were the only ones allowed to access the proxy link.

    Suppose a device connected to the web wants to access our client’s server via the proxy link. The IP address of this device making the request to the proxy link is verified against the list of IP addresses allowed by the client utilizing the services of the reverse proxy product. If the IP address is allowed, the device’s request is further transferred to the client’s server, else, the device receives a 403 Forbidden error.

Ip Restriction Use Case Flow

How to enable the IP Restrictions?


These configurations are saved in the configuration file of the reverse proxy server. In this way, the users can restrict access to their web servers, making them more secure overall with IP restrictions.
