* Check whether devices with IPs from different ranges reach the Internet through the default gateway. If you only have one device at your disposal at the time, you can configure a static IP address (guide for Linux users '''[[Setting up a Static IP address on a Ubuntu 16.04 PC|here]]'''; for Windows '''[[Setting up a Static IP address on a Windows 10 PC|here]]''') for that device in one range and later in the other. According to our configuration, if a device's IP falls in the range of 192.168.1.1 - 192.168.1.127, its Public IP should be that of the router's; if the IP falls in the range of 192.168.1.128 - 192.168.1.254, its Public IP should be that of the OpenVPN server. You can check the Public IP address in '''[http://www.whatsmyip.org/ this website].
