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.
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:
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.
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.
