Fixes in 3.0.6

The following issues have been fixed in this release.

ID number Description
720093 Previously, F5 Access did not support opening links for App Store app during authentication with Web Logon. When the user selected the link, an error message "Unsupported URL" was displayed. This issue has been fixed, and now the App store opens without any errors.
786153 Previously, when there were recurring network errors, F5 Access for iOS displayed multiple error messages, blocking the device UI. This issue has been fixed, and now F5 Access reconnects in the background without displaying any errors.
788805 Previously, F5 Access did not reconnect and remained disconnected on waking up when using a cellular network with poor connectivity. This issue has been fixed, and now F5 Access attempts to reconnect for 120 seconds before going to the disconnecting state.
792061 Previously, when there was a network error, the cached password was deleted and the user was prompted for username and password. This issue has been fixed, and now F5 Access uses cached credentials for the VPN connection and does not give any prompts to the user.
793313 Previously, when there was a loss of network connectivity while the Per-App VPN or an On-demand VPN is connected, then F5 Access did not reconnect during the inactivity timeout and remained disconnected, giving an error message. Now, F5 Access attempts to reconnect multiple times during the specified inactivity timeout and this issue is fixed.
796941 In scenarios, with multiple sleep-wakeup cycles, F5 Access triggered reconnection even after VPN was successfully re-established. This issue is resolved, and now F5 Access does not attempt to reconnect after the VPN is established.

Known issues affecting F5 Access 3.0.6

The following are known issues in this release.

ID number Description
504919 F5 Access does not resolve the BIG-IP APM hostname each time it reconnects after the connection is broken. This limits the use of load balancing with BIG-IP DNS as it keeps using the same IP address for the connection.
557905 On iOS 9, if a managed app is being updated while per-app VPN is active, the updated app might not make use of the active session until the active session is expired and a new one is created. As a workaround, wait until the current session expires, and restart the updated app.
587775 F5 Access for iOS may frequently sleep/wakeup VPN plugin in the sleep mode of the device and send DNS queries every 10 seconds to a few minutes. This causes the APM session to be alive using additional resources. The issue was reported to Apple and is tracked through 48529129.
695712 Due to an iOS issue (Apple Radar 36006149), it is currently not possible to switch between configurations widget added to the Today view.
696882 F5 Access does not support user interaction prompts for per-app VPN scenario. Server configuration should not require any user interaction to establish a VPN.
699062 Per-app VPN that requires user interaction works only with a single per-app VPN configuration, and only with clients running iOS 12. We currently do not support user interaction in a per-app VPN scenario with any other per-app VPN configurations. Administrators should configure the BIG-IP so as not to require user interaction to establish VPN for configurations that require more than a single per-app VPN.
700849 When you use an MDM to push a device-wide VPN that includes the SavePasswordEnabled feature, the setting enforceWebLogon does not work after the device is restored from backup.
701247 With the use of Apple Transport Security (ATS) in version 3.x, insecure HTTP does not work for most connections. However, in some cases an HTTP (not HTTPS) IP address still works. This may or may not be removed in the future by Apple.
701636 The Session expired or closed by server message will not appear when the session is killed by an administrator or by timeout. The tunnel will be silently closed instead. Similarly, the message will not be shown if no lease pool is specified for the NA resource or the NA's lease pool is exhausted.
704309 Before iOS 12, F5 access did not send the client certificate to BIG-IP if the weblogon mode was enabled in the configuration, due to framework limitations. In iOS 12, Apple partially fixed this issue, but the client certificate is attached twice. We are still waiting for Apple to update us.

F5 Access displays an Authentication failed error message and the VPN is not established, in scenarios where user input is required to authenticate, and the user has disabled notifications for F5 Access. As a workaround, enable notifications in Settings > F5 Access to show a credential popup for authentication.

706718 If the per-app VPN configuration does not have SafariDomains specified, it is displayed as Enterprise VPN in F5 Access.
707434 The confirmation message F5 Access would like to Add VPN Configurations that appears when you attempt to save the first VPN configuration, is not localized in iOS 11. Regardless of the selected system language, the message appears in English.
708016 After you perform Network Settings Reset on the iPhone, the following items of an MDM VPN configuration may get corrupted:
  • Web logon
  • Enforce logon mode
  • Password expiration time
  • Web logon auto-populate
  • Save password policy

As a workaround, contact the MDM administrator and re-deploy the MDM configuration.

734750 Certificates imported to F5 Access are not deleted when F5 Access is uninstalled.
743249 When F5 Access Legacy (2.1.x) and F5 Access 3.0.x are running on the same device, if there are configurations created in each VPN client with the same name (for example, MyVPN), after the iOS device restarts, a "2" is appended to the name of whichever configuration was created last (for example, MyVPN and MyVPN2).
743801 On a redirect, the Server URL name in the connection details of F5 Access is displayed incorrectly. However, there is no functional impact on the server connection and establishes the connection accurately.
743918 The VPN connection cannot be established if the PAC file cannot be downloaded without the established VPN.

As a workaround, set the Ignore Client Proxy Autoconfig Script Download Failure setting to enabled, so the client does not attempt to download the PAC file before establishing the connection. The tunnel will be created with PAC specification as provided in the NA resource.

As a workaround for BIG-IP versions 11.6.3 and 11.5.7, where the Ignore Client Proxy Autoconfig Script Download Failure setting is not available in the user interface, add Variable Assign agent with the following entries to your Access Policy:

  • Custom variable:


  • Custom expression:

    return {<client_proxy_settings><client_proxy>yes</client_proxy><client_proxy_script>CLIENT_PROXY_AUTOCONFIG_SCRIPT</client_proxy_script><client_proxy_ignore_auto_config_error>1</client_proxy_ignore_auto_config_error></client_proxy_settings>}

    This will enable the Ignore Client Proxy Autoconfig Script Download Failure setting.

745999 The session is not deleted from the BIG-IP system v11.6.3 when F5 Access disconnects with the Weblogon mode enabled.
747798 When using F5 Access 3.0.2 and upgrading to iOS 12.0 or higher, users are not able to connect to VPN if Wifi HTTP Proxy is set to Automatic. This issue is currently reported to Apple and tracked through 47359424.
748153 Per-App-VPN with internal use of TLD .local domain does not work. This issue is currently reported to Apple and tracked through 45641400.
758831 On iOS 12, F5 Access connects to incorrect port when port forwarding is used with NAT, as F5 Access reads port from the session variables. This results in connectivity issues. As a workaround, add a variable assign object to the policy:

758833 F5 Access has some limitations on cookie storage, which may prevent the logon page from saving state. For example, the "Remember me for 30 days" option, cannot be used with F5 Access as the user is required to enable cookies to remember the device.
772505 When F5 Access for iOS fails to communicate with an External Logon Server, the client-side logs fail to provide debugging hints related to communication between F5 Access and the External Logon Server.
