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
  • 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 (local network IP)
server (for example)
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
status openvpn-status.log
log openvpn.log
verb 3
keepalive 10 120

Client profile *.ovpn (tested on android openvpn app).

dev tun
proto udp
remote 'hostname(NOIP) or Public IP' 443 (sample port)
resolv-retry infinite
ca /file_path/ca.crt
cert /file_path/client.crt
key /file_path/client.key
ns-cert-type server
cipher bf-cbc
verb 3
mute 20

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.


If you use a version older than 8.2-release, you need to add the OpenVPN configuration directory to AutoBackup. To do so, add


to AutoBackup.
