You may want to use TLS pre-authentication on your VPN. Easy-rsa is now managed as an independent package Creating Certificates using Ubuntu LinuxĬreating certificates only requires the easy-rsa package.

Generating DH parameters, 1024 bit long safe prime, generator 2 Always use a unique common name for each client.ĭiffie Hellman parameters must be generated for the OpenVPN server. Remember that for each client, make sure to type the appropriate Common Name when prompted, i.e. If you would like to password-protect your client keys, substitute the build-key-pass script. Create as many client certs as needed, naming each individually. Generating client certificates is very similar to the previous step. Generate certificates & keys for 3 clients Two other queries require positive responses, "Sign the certificate? " and "1 out of 1 certificate requests certified, commit? ". When the Common Name is queried, enter "server". Vars ->ENTER build-key-server server ->ENTERĪs in the previous step, most parameters can be defaulted. Next, we will generate a certificate and private key for the server. In the example above, I used "OpenVPN-CA". The only parameter which must be explicitly entered is the Common Name. Organizational Unit Name (eg, section) :MyUNITĬommon Name (eg, your name or your server's hostname) :OpenVPN-CAĮmail Address that in the above sequence, most queried parameters were defaulted to the values set in the vars or vars.bat files. If you enter '.', the field will be left blank. There are quite a few fields but you can leave some blankįor some fields there will be a default value, What you are about to enter is what is called a Distinguished Name or a DN. You are about to be asked to enter information that will be incorporated The final command (build-ca) will build the certificate authority (CA) certificate and key by invoking the interactive openssl command: Vars ->ENTER clean-all ->ENTER build-ca ->ENTER All of the following build actions produce files that will be placed in the "keys" directory under C:\>\OpenVPN\easy-rsa\. Save the file and return to the CMD Prompt. Don't leave any of these parameters blank. Now edit the vars file (called vars.bat on Windows) and set the KEY_COUNTRY, KEY_PROVINCE, KEY_CITY, KEY_ORG, and KEY_EMAIL parameters. Run the following batch file to copy configuration files into place (this will overwrite any preexisting vars.bat and openssl.cnf files): Open up a Command Prompt and cd to C:\>\OpenVPN\easy-rsa. After then, you can set your time to GMT-8 or what ever time zone you are in.Įasy RSA is installed with the OpenVPN package on Windows. You will need to set your router to use GMT until the time difference elapses or you will receive TLS Auth errors when tring to connect until the time difference passes. Your certificates will not be valid until 8 hours after generation, assuming that you have your time set to GMT-8 on the router and are using a NTP time server to manage the router time setting. For instance, if on the West Coast of USA, your local time is GMT-8. This will result in the certificated not being valid until your local time equals that of GMT at the time of the certificate signing. PRECAUTION: When generating certificates using Easy RSA in Windows, the certificate will be signed using GMT time, not your local time.

Once you have verified you have enough nvram space, you need the OpenVPN software installed on your computer, as it is used to create all the needed certificates.

Doing a factory reset may free up NVRAM, however, you will lose your existing configuration. You must use the Script method to store the certificates and activate VPN. If you do not have enough NVRAM space available, you cannot use the web-GUI method that is outlined below. To test how much NVRAM space is left (and used) telnet or ssh into your router and type: Using a KEY_SIZE of 2048 you need about 6000 bytes available in NVRAM on the server-side. Using a KEY_SIZE of 1024 you need about 5200 bytes available in NVRAM on the server-side before you push SAVE in the web-GUI, or you might brick your router. Overfilling the NVRAM area is likely to brick your router. We have more detailed instructions on this for example at Installation.Īll the data from the web-GUI is permanently stored in the NVRAM area.
