install openvpn access server raspberry pi

Now create a packet with all the needed files for the client, which we will place in /home/pi and give the user pi the needed rights to the file. RASPBERRY-PI-IP should be replaced by the IP address of your Pi or, if you are using a DynDNS service, by the given domain. Insert following line at the end of the crontab file (replace “eth0″ if you did above):Ĭrontab sudo iptables -t nat -A POSTROUTING -s 10.0.0.0/8 ! -d 10.0.0.0/8 -o eth0 -j MASQUERADEĪgain change to the root-user and to the directory /etc/openvpn/easy-rsa/keys in which we will create the file raspberrypi.ovpn and fill it with the code of the second paragraph. One of the final steps will be to delete the “#” before _forward=1 in nf.Ī part of the above settings have to be endorsed as a crontab to work permanently. Sudo sh -c ‘echo 1 > /proc/sys/net/ipv4/ip_forward’ Wifi) you will have to replace “eth0″ with the name of your network device. If you are not using an ethernet-cable (e.g. Now, create the internet-forwarding for the CPN clients. You can change the DNS-servers to any DNS you like. Key /etc/openvpn/easy-rsa/keys/server.key

We have to switch the directory again and create the file nf with the following content:Ĭert /etc/openvpn/easy-rsa/keys/server.crt The calculation of the last components can take a few minutes.

All other inputs can simply be confirmed. After the first input you will be asked for the abbreviation of your country (US = USA, DE – Germany, AT = Austria, CH – Switzerland). Now we are able to generate the components for the encryption of OpenVPN. We change the directory, log in as root user and execute some configurations. Now we open the file easy-rsa/vars with nano and apply some changes. Sudo cp -r /usr/share/doc/openvpn/examples/easy-rsa/2.0. We are switching to the directory of OpenVPN and paste a directory we will be needing later into it. Now we are installing OpenVPN and OpenSSL. To be able to install the latest programversions we should update our packet sources: In the following tutorial you will learn how to run OpenVPN Server on your Raspberry Pi: The VPN-tunnel leads your traffic encrypted to a server which is processing your requests. To prevent others from doing that you can send your traffic through a secured VPN-tunnel.

If you are in a public network, for example at university or the airport, your traffic can be recorded and decrypted.
