Nowadays, VPN technology becomes more popular. Ordinary users use VPN to safely access the Internet. It also helps get around locally blocked websites and services and protect against possible external malicious behavior. It differs from each other by operating systems supported and algorithms used. We will take a look at two independent approaches to set up a VPN server. The first one is based on PPTP protocol that is already considered obsolete and not secure but is really easy to configure. The other one employs modern and secure software OpenVPN but requires installing a third-party client application and a more thorough setup process.

As noted previously in our OpenVPN article , this is an open-source Windows software package used to create a secure, site-to-site tunneled VPN connection that provides remote access between two locations. Some functionality that is handled within the admin interface includes tunneling, routing, encryption , user management, authentication , and many other features. In the WebGUI, an admin can check routing options, privileges, network configurations, user validation, and other parameters. This application allows users to link to the VPN server directly in one of three ways. The three options are:. On a Windows server, we begin by downloading the Windows installer and then running it on our Windows server. Once that has completed, we begin the configuration portion of the setup. Finally, double click the icon which appears in the system tray to start the connection. The subsequent dialog box will close upon an effective start. If you have any connection difficulties, ensure you set up a rule on the server's firewall allowing incoming UDP traffic on port
Azure Active Directory's Application Proxy provides secure remote access to on-premises web applications. After a single sign-on to Azure AD, users can access both cloud and on-premises applications through an external URL or an internal application portal. Web proxies can be used to access sites that may be blocked due to your geographical location or censorship blocks at work. Many internet surfers use a web proxy to access sites such as Facebook or YouTube if they are unable to access them in their home country. However, there are no guarantees that any particular website will work with a proxy. Although hosted in shared hosting environment, it enables users to have better control and access compared to shared hosting. Today, we will see the implementation of Apache as a reverse proxy in the front-end of another apache server that will be its back-end. We will just try to redirect the flow arriving at a destination server of a domain name to a server located further upstream in the architecture.
