Using the OpenVPN Client Export Package¶
The OpenVPN Client Export add-on package, located at VPN > OpenVPN on the Client Export tab, automatically creates a Windows installer to download, or it can generate configuration files for OSX (Viscosity), Android and iOS clients, SNOM and Yealink handsets, and others.
Choose from any existing remote access server definitions, and then pick from a list of client certificates which are present under the Certificate Management system. For authentication-only servers, all clients use a common configuration/installer.
Click the link next to a certificate’s row to download a windows client, mac client configuration, or other types of configurations.
Remote Access Server¶
Choose the OpenVPN server for which clients/configurations will be generated. The options presented will vary depending on the type of configuration in use:
- Remote Access (SSL/TLS + User Auth), Local Users: Client list consists of users from the User Manager which have certificates associated with their user entry from the CA matching this server.
- Remote Access (SSL/TLS + User Auth), RADIUS/LDAP: Client list consists of certificates from the Certificate Management certificate list with a CA matching this server.
- Remote Access (SSL/TLS): Client list consists of certificates from the Certificate Management certificate list with a CA matching this server. This mode also enables export for SNOM and Yealink handsets as they do not support user authentication
- Remote Access (User Auth): Only one client is shown, a common client for all users that authenticate via the chosen method.
Host Name Resolution¶
Controls the format of the server address in the client configuration’s “remote” statement.
- Interface IP Address: Uses the actual configured interface IP address/VIP literally (most common choice)
- Automagic Multi-WAN IPs (port forward targets): Locates any port forwards with a target of the VPN’s binding address and port. Add remote staetments for all of them. Useful for Multi-WAN or for multiple ports on the same WAN.
- Automagic Multi-WAN DDNS Hostnames (port forward targets): As above, but uses the first found DynDNS hostname as the remote address rather than the destination IP directly.
- Installation hostname: Uses the hostname and domain configured under System > General.
- DynDNS: All of the Dynamic DNS hostnames from Services > Dynamic DNS are listed as individual choices.
- Other: Presents a text box in which an arbitrary address or hostname may be placed.
Verify Server CN¶
Controls how the client will verify the server certificate common name, if it is done at all. Some clients do not support this parameter, or only support certain syntax with its use. It is always adivsed to run the newest client software possible to avoid issues, but this can help get older clients connected securely.
It is not recommended to disable this option. Without it, any server certificate name will be accepted by the client.
- Automatic - Use verify-x509-name (OpenVPN 2.3+) where possible: Uses the current recommended method of verification. Works on any OpenVPN client 2.3 and newer.
- Use tls-remote (Deprecated, use only on old clients <= OpenVPN 2.2.x): Only use this if an older client that is not under direct control must be supported. The option has been deprecated by OpenVPN and will be removed in the next major version.
- Use tls-remote and quote the server CN: As above, but adds quotes around the common name. Useful if the certificate common name contains spaces. Varies by platform.
- Do not verify the server CN: Omits any verification of the server certificate common name. Not recommended.
Use Random Local Port¶
Instructs the client to use a random local source port (lport) for traffic from the client. Without this set, two clients may not run concurrently as they would both attempt to use the same local source port.
This option is not supported on older clients. It is automatically disabled for Yealink and Snom configuration exports.
Certificate Export Options¶
Fine-tuning for how the certificates may be used and access on the client.
- Use Microsoft Certificate Storage instead of local files: For Windows clients, attempts to import the certificates into Windows rather than having the files be read directly from the disk by the OpenVPN client. This is more secure, but also more error-prone.
- Use a password to protect the pkcs12 file contents or key in Viscosity bundle: When checked, allows a password to be entered which will protect the contents of the certificate.
If the clients will be behind a proxy, check this option and fill in the options for use by the client to connect through the specified proxy
The options vary by proxy type and authentication mechanism. At minimum, a Type, IP address and Port must be entered when the Use Proxy box is checked.
Management Interface OpenVPNManager¶
Changes the generated .ovpn configuration to allow for usage of the management interface and include the OpenVPNManager program in the Windows Installer options.
With this set, OpenVPN can be used also by non-administrator users. This is useful for Windows Vista/7/8 systems where elevated permissions are needed to add routes to the system.
This is not currently compatible with the 64-bit OpenVPN installer. It will work with the 32-bit installer on a 64-bit system.
Additional configuration options¶
Additional options may be added in this text area and they will be placed into the OpenVPN client export configuration. Separate options by a line break or semicolon.
This can be used for directives that are not currently added to the configuration automatically, such as reneg-sec, or for custom remote statements.
Types of Clients and Configurations¶
The Client Install Packages section contains a list of all available clients for the selected VPN. See the Remote Access Server section above to determine which clients should be expected to appear here.
If the list is empty, there are likely no users and/or certificates that exist which use the same Certificate Authority as this VPN server.
- Archive: Exports a .zip file containing The .ovpn configuration file for OpenVPN, the .p12 file containing the CA and User Certificate+Key, and TLS key if enabled.
- File Only: Exports only the .ovpn configuration file for OpenVPN without any related certificates or keys. Useful if delivering an updated configuration file when the other data has not changed.
- Android: Exports an inline configuration suitable for use by the OpenVPN For Android app.
- OpenVPN Connect (iOS/Android): Exports an inline configuration suitable for use by OpenVPN connect on Android (Google Play) or iOS (App Store)
- Others: Exports an inline configuration file suitable for use by any other current OpenVPN client, such as the Windows client, Viscosity, or Tunnelblick.
The Windows installer packages together the client software and the configuration files in one .exe to ease deployment. When executed on the client computer, the installer will first install OpenVPN and the TAP driver if they are not present, and then it copies the exported configuration file into place automatically. If OpenVPN is already installed on the client computer, then the configuration is copied into place but no other changes are made to OpenVPN.
There are currently four different installers:
- x86-xp: 32-bit installer for use on Windows XP and later.
- x64-xp: 64-bit installer for use on Windows XP and later.
- x86-win6: 32-bit installer for use on Widnows Vista/7/8/10. Includes a newer TAP driver.
- x64-win6: 64-bit installer for use on Widnows Vista/7/8/10. Includes a newer TAP driver.
When in doubt, the 32-bit XP and later installer will work on pretty much anything. TAP drivers for both 32 and 64-bit systems are included and will be installed as needed.
