Touch the Rename link in the upper-right corner. This will cause the profile name to become editable. Pressing "Done" on the soft keyboard will save the change. All proxy options are available here. Proxy options can also be specified in the OpenVPN profile itself using the http-proxy and http-proxy-option directives. Using the iOS keychain to store your private key has the added security advantage of leveraging on the hardware-backed keystores that exist on many iOS devices, allowing the key to be protected by the iOS-level device password, and preventing key compromise even if the device is rooted.

If you already have your client certificate and private key bundled into a PKCS 12 file extension. Note sure that the file extension has to be changed to. The CA certificate authority certificates are NOT imported unless you manually extract the CA certificates and import them separately, one-at-a-time. Therefore, the CA list must be given in the profile using the ca directive. If you don't have a PKCS 12 file, you can convert your certificate and key files into PKCS 12 form using this openssl command where cert , key , and ca are your client certificate, client key, and root CA files.

Then import the client. Once this is done, remove the cert and key directives from your. Touch the Certificate row and select the MyClient certificate. At this point, you should be able to connect normally. For this reason a profile requiring a certificate stored in the Keychain to connect won't be able to do so automatically after restart. This is a security measure to prevent an unknown person to access a VPN network using a device that was previously switched off. For this reason they are not visible in the iOS Settings.

This will cause red "-" icons to appear to the left of all PKCS 12 files. Touch the "-" icon to actually delete a file.

When you generate a PKCS 12 file, you will always be asked for an "export password" to encrypt the file. This is to prevent interception and recovery of the private key during transport. When you import a PKCS 12 a password must always be specified. If you have set an empty password, just tap OK without entering any text. This approach is much better from a security perspective, because the Keychain can then leverage on hardware features in the device such as hardware-backed keystores.

How do I use a client certificate and private key from the iOS Keychain? This is discussed in detail in the FAQ item above: You could add the following directives to the OpenVPN server-side configuration to push these settings to clients:.

Suppose also that you want several web domains to connect directly example1. If you don't want to or can't modify the OpenVPN server configuration, you can also add proxy directives directly to the client. In some cases, if you push proxy options, it may also be necessary to push a DNS server address as well:. The connection proxy capability is a separate feature that is accessed through the Settings App under OpenVPN or by using the http-proxy and http-proxy-option directives.

On a split-tunnel, where redirect-gateway is not pushed by the server, and at least one pushed DNS server is present:. For example, the following directive on the server will tell the client to route all DNS requests to Note that with redirect-gateway , the above discussion is moot, since all DNS requests are always routed through the VPN regardless of the presence or absence of added search domains. In order to specify a different domain to append, the server can push a special directive including the new name:.

You can provide OpenVPN with a list of servers to connect to. On connection failure, OpenVPN will rotate through the list until it finds a responsive server. For example, the following entries in the profile will first try to connect to server A via UDP port , then TCP port , then repeat the process with server B. OpenVPN will continue to retry until it successfully connects or hits the Connection Timeout, which can be configured in the Preferences.

When OFF, no specific ciphersuites are forced. If a specific TLS version is selected it will override any profile setting. If Profile Default is selected, the app will use the tls-version-min profile directive if it exists, or TLS 1. Port — HTTP proxy port number. Allow Basic auth — If ON, allow authentication methods that transmit the proxy password in cleartext.

It will also be visible as a profile in the OpenVPN app. Note that the profile must be the currently-enabled VPN profile in order for the VoD functionality to work. First of all, thank you for your interest in our product. When you are using a developer preview of iOS which isn't out yet for the general public, while we do appreciate you bringing these issues to our attention, we will not be issuing a fix for a bug found in a developer, preview, or beta release version of the iOS platform immediately.

It will be put it in a queue of known issues for review and fixing. The reason for this is that if you need to use iOS for production purposes and need the product to function as expected, you really should be using the release intended for the general public, and not some development preview or beta release. It is quite possible that if we were to create fixes for an unfinished release of iOS, something else will change in iOS before it goes to a general release, which could break our software product again and make our efforts useless.

By using the developer preview release, you will without a doubt encounter some issues, either with our software or other people's software, and this is normal and expected. We of course are testing on such versions as well, and are usually aware of these issues and we will be making sure that when such a new iOS release does finally go out for general release, that our software product will be updated to function properly on that version.

Given that mobile devices are easily lost or stolen, how best to secure VPN profiles against compromise if the device falls into the wrong hands?

The most sensitive piece of data in a profile is the private key. Consider removing the client certificate and private key from the profile and save them in the device Keychain instead this is discussed below. Use a strong device-level password. This is critical to protect data stored in the device Keychain. Is it safe to save passwords? After updating my app the certificate list is empty!

Why is the save password switch sometimes disabled? The save password switch on the authentication password field is normally enabled, but can be disabled by the following: The following OpenVPN directive, if present in a profile, will disable the password save switch: Yes, but with some important exceptions: During pause, resume, and reconnect states for example when transitioning between WiFi and Cellular data , the VPN tunnel may temporarily disengage, allowing network traffic to bypass the tunnel and route directly to the internet.

It will make a best-effort to keep the tunnel active during pause, resume, and reconnect states to prevent packet leakage to the internet. Why doesn't the app support tap-style tunnels? Are there any OpenVPN directives not supported by the app? Here is a partial list of directives not currently supported: Note as well that the client does not support connecting to a server that uses the fragment directive. Since the functionality of mssfix can be achieved on either the client or server side, specifying it on the server side will enable it even if the client doesn't support the directive.

This is done to reduce bloat and improve energy efficiency. Can I have multiple profiles? How do I delete a profile? How do I rename a profile? You could add the following directives to the OpenVPN server-side configuration to push these settings to clients: On a split-tunnel, where redirect-gateway is not pushed by the server, and at least one pushed DNS server is present: In order to specify a different domain to append, the server can push a special directive including the new name: How do I set up my profile for server failover?

Connection Settings Seamless tunnel requires iOS 8 or higher — Make a best-effort to keep the tunnel active during pause, resume, and reconnect states. Typically, during VPN pause, resume, or reconnect for example when transitioning between WiFi and Cellular data , the VPN tunnel may disengage for a short period of time, normally on the order of seconds or less.

During this time, network traffic can potentially bypass the tunnel and route directly to the internet. Consider also enabling the Layer 2 reachability setting below when using Seamless Tunnel.
