I bought a TPLink WiFi router with Open VPN capabilities so I could use it to connect remotely to a server in the private network of my company. I installed Open VPN Connect in my laptop and configured it with the certificate generated by the TPLink router and was able to successfully establish the connection (the TPLink router has a fixed public IP address). Once connected, I was able to access this router through its LAN port using a web browser, so I am certain that the tunnel has been established correctly, that I am inside the LAN (connectivity wise). The inside network is very simple: the server is directly connected to the LAN port of this TPLink router and there are some devices connected via WiFi, that´s it (no intermediate routers or routing issues). The Ping test to the server (address 192.168.1.2) works well, so it seems the issue is not connectivity (routing). But when I open the client application (it is called Saint Enterprise, for Inventory, finance, etc.), it gives me a message saying "Error connecting to server". When I am in the local network (connected through WiFi) it works well
At risk is stating something you already know, the "tap device" is just a virtual network adapter that OpenVPN uses on Windows. (I personally find the name of this thing as little confusing since it is used for both tun and tap... but whatever)
At any rate, when you look at Window's network adapters, the tap device should be there. If it isn't, you typically just need to install it. It should be obtainable via the OpenVPN client install file.
