We would like the ability to route traffic from a WAN (publicly) accessible Web server with a static IP address, to various other Web servers that are connected to the public service as OpenVPN clients. We can change any configuration on the public Web server though have no control over the client web servers, other than that the are connected to the local OpenVPN service. So the flow would be that you visit the Public Web page and based on your permissions you have a list of web servers that you can access that are connected to the OpenVPN internal network. I have got this to work using Nginx and routing the traffic though need a way to keep track of the IPs connected to OpenVPN and how to best route traffic securely to this Webservers. Two aspects of the project would be the network setup for OpenVPN client tracking with Proxy (Nginx) and the other aspect would be how to access these webservers based on permissions using PHP and/or other LAMP solutions.

Hello, The solution could be as following: 1. User authenticates himself on main website 2. The website pull list of allowed IPs from the the database 3. Based on list of allowed IPs system either 1) produces modified config file(s) for NGINX and sends a signal to re-read configuration 2) or, disables/enables ip routing via "iptables" command With approach #1 it will be possible to produce personalized error message for user if he is trying to access non-authorized IP, but if you have thousands of simultaneous users there could be delays in re-reading the config, and users may not get access right away With approach #2 the user will get generic error message "Bad gateway" (or it may be renamed to "No access"), but configuring access will be instant Please let me know what you think I have 15+ years of experience in IT, including extensive experience in Unix, NGINX and Web apps. For details please visit my profile on freelancer or on LinkedIn (just search for Alexei Maximov, Calgary). I am working from home, so I can be reached by phone almost any time. Thanks Alexei
