Although you can install OpenVPN on your Enigma2 box it is not to be recommended. You should use a router for that (WiFi router or NAS) or a custom router firmware. So use something that's being updated regularly and has a large community, as safety is much higher when you have the latest security updates.
This is an experimental setup from the forum and you must be familiar using the command line, so please report any error or problems in this thread on the forum.
- Install openvpn using the command line
opkg install openvpn
- Create files ca.crt, server.crt, server.key, same files for clients, client.crt, client.key, following this link
- All files have to be .pem extension, so convert the files, please follow this guide up to finish this three last steps:
set RANDFILE=c:\demo\.rnd set OPENSSL_CONF=C:\OpenSSL-Win32\bin\openssl.cfg c:\OpenSSL-Win32\bin\openssl.exe
- Now, in this mode, you can convert .crt and .key files to .pem for server files, and put these files in your stb\receiver at /etc/openvpn/
$ openssl> x509 -in filename.crt -inform DER -out filename.crt.pem -outform PEM $ openssl> rsa -in filename.key -out filename.key.pem -outform PEM
The ca.cert file, we have to open the certificate in windows OS and select details tab> copy file>convert to binary DER x509 and select destination folder to save.
Then we convert the ca.cer file to .pem file:
OpenSSL>x509 -inform DER -in ca.cer -outform PEM -out ca.pem
All these conversions to .pem extension is based on openvpn --help binary information of our installation of openvpn in our STB, maybe it's not necessary.
dh2048.pem have to locate at openvpn config directory too, /etc/openvpn
I add two extra .pem files to the directory 01.pem and 02.pem, they have been generated on the files creation, they contains key info, I don't know if there is duplicity of information.
Lets to put the server config file parameters /etc/openvpn/server.conf
local 192.168.xxx.xxx (local network IP) server 10.8.0.0 255.255.255.0 (for example) tls-server proto udp port 443 (sample port) dev tun ca ca.pem dh dh2048.pem cert server.crt.pem key server.key.pem extra-certs 01.pem extra-certs 02.pem ifconfig-pool-persist ipp.txt comp-lzo float ping-timer-rem persist-key persist-tun status openvpn-status.log log openvpn.log verb 3 keepalive 10 120

The port we are going to use to vpn connection have to be opened, of course, and you can forward to other external different port as you know.
