The remote directive in the client config file must point to either the server itself or the public IP address of the server network's gateway.If youвЂ™ve set up an OpenVPN server to provide secure access to remote workers, youвЂ™ve got half the battle won. The OpenVPN client config does not have the correct server address in its config file.A NAT gateway on the server's network does not have a port forward rule for TCP/UDP 1194 (:4000-4100) to the internal address of the OpenVPN server machine.Be aware that many OSes will block incoming connections by default, unless configured otherwise.

A software firewall running on the OpenVPN server machine itself is filtering incoming connections on port 1194 (:4000-4100).By default OpenVPN uses UDP or TCP port number 1194. A perimeter firewall on the server's network is filtering out incoming OpenVPN packets.One of the most common problems in setting up OpenVPN is that the two OpenVPN daemons on either side of the connection are unable to establish a TCP or UDP connection with each other. TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity) You can disable the auto start by typing: Sudo systemctl enable rviceДЄfter that you have to restart the system to see if everything works ok:ДЄfter reboot you should check if the service started ok:

Now reload the systemctl daemon and tell it to put our service in startup: Sudo chmod 644 /lib/systemd/system/ rvice The permission on the service file needs to be set to 644: You can just copy the following text and make required changes in it:Д®xecStart=/usr/sbin/openvpn -config /etc/openvpn/ US-East.ovpn Using your favorite text editor create the following file (mine is vi, but you could use nano, pico, joe or gedit) *This step requires that you setup automatic logon from the previous step. Setting up automatic OpenVPN connection on system start Just ignore it, and log-out once more, this will kill the stopped job. Notice, that sometimes, you will be left with the terminated process in the process list and when you log out you will get a warning message 'You have stopped jobs'. Terminating the connection is as easy as typing: Sudo nohup openvpn -config /etc/openvpn/ US-East.ovpn & If you want to start the connection in the background and also make it not terminate on exiting the terminal you should use this command instead: This will start the connection in the foreground. Sudo sed -i 's/auth-user-pass/auth-user-pass /etc/openvpn/credentials/g' /etc/openvpn/ US-East.ovpn ovpn configuration file to use the credentials file:

Replace username and password with your own credentials Sudo printf '%s ' ' username' ' password' > /etc/openvpn/credentials If you want an automatic logon when you start the OpenVPN connection, you need to make the required changes to configuration files: disown -h makes it so the process isnвЂ™t killed when the terminal is shut down. bg resumes suspended process and sends it to the background. This invokes elevation and in the same time connects to the desired VPN destination, but it does so in the foreground. Sudo openvpn -config /etc/openvpn/ US-East.ovpn Since sudo elevation that requires you to input your credentials and putting the process into the background in the same line doesn't work, this is the recommended connection method if you want to manually type in your username and password: Next, you need to connect using the current configuration file, and you'll be asked for our credentials.
