9.4.5. Starting up VPN
First, place the configuration files in the client and server. Like in the examples, the location
for these files can be, for example, C:\Program Files\OpenVPN\config in Windows and
/usr/local/openvpn/config in Linux. Next, copy the authentication files ( ca.crt,
server.crt, server.key, client.crt and client.key) into the same directories.
9.4.5.1. Starting up the Server
The OpenVPN server must be accessible from the internet:
• open UDP port 1194 on the firewall (or the TCP/UDP port you’ve configured), or
• set up a port forward rule to forward UDP port 1194 from the firewall/gateway to the machine
running the OpenVPN server
• make sure TUN/TAP device is allowed access through firewalls
To start the OpenVPN server right-click on the .ovpn file on Windows and choose "Start Open-
VPN on this config file" or by right-clicking the GUI icon on taskbar and start correct config file
from there. It’s also possible to start from command line:
openvpn [server_config_file]
Where "server_config_file" is in our Windows examples is server.ovpn.
