In December 2018, Apple posted the release of F5 Access for iOS 3.0.4. Users should download this new version from the app store.
For a comprehensive list of documentation that is relevant to this release, refer to BIG-IP Access Policy Manager Documentation.
There are no behavior changes in 3.0.4.
|744910||For F5 Access version 3.0.1 and later, when a reconnect occurs due to a network change or brief network outage, F5 Access reconnects successfully, and the status of connected time is reset to zero. This connection time is provided by Apple iOS PacketTunnel framework and functions as designed.|
|700903||Previously, when network connectivity changes occurred, cached password was removed. This issue has been fixed.|
|749524||Previously, when DTLS connections were established, there was a performance degradation issue. With F5 Access 3.0.4 release, the performance with DTLS channel has improved significantly.|
|751187||Previously, F5 Access displayed DNS error notifications when the device is not able to resolve the FQDN for F5 Access Server, and on-demand VPN connection attempt failed. These error messages were displayed on the device until the VPN on-demand connection was not connected. Now, there are no DNS error notifications for on-demand triggered connections, and this issue has been fixed.|
|738442||Previously, under certain circumstances, per-app VPN sessions can intermittently close with APM log Session deleted (network_error; code - 4) or new sessions can be established while current sessions are still active. This issue is resolved.|
|739513||Fixed this issue where F5 Access for iOS web logon failed in some cases when there are multiple redirects to external pages.|
|744672||Previously, F5 Access failed to reconnect VPN when network changed state (connect, disconnect, reconnect, etc.) from wifi to 4G or vice versa. This issue has been fixed.|
|745614||Previously, when Access Profile is configured with a Domain Cookie on BIG-IP, then F5 Access web logon mode failed to connect. This issue is resolved.|
|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||iOS may frequently sleep/wakeup VPN plugin in the sleep mode of the device and send DNS queries. This causes APM session to keep alive for a long time. The DNS queries are sent from every 10 seconds to a few minutes. The issue was reported to Apple to confirm and tracked through 25739124.|
|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 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 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.|
|704554||In a scenario where F5 Access requires user input to authenticate, the error message Authentication failed is displayed if notifications are not enabled for F5 Access. As a workaround, you should enable notifications in.|
|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 a 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:
As a workaround, contact the MDM administrator and re-deploy the MDM configuration.
|734519||On the iPad, in the Credentials prompt, the Save Password box is not aligned correctly.|
|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 whatever configuration was created last (for example, MyVPN and MyVPN2).|
|743801||On a redirect, the Server URL name in connection details of F5 Access is displayed incorrectly. However, there is no functional impact on the server connection and establishes the connection accurately.|
|743918||VPN connection cannot be established if 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 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:
|745999||The session is not deleted from the BIG-IP system v11.6.3 when F5 Access is disconnected with the Weblogon mode enabled.|
|747350||F5 Access may not go to reasserting state for 30 - 60 seconds when a mobile network connection is lost over TLS established tunnel. As a workaround, use DTLS protocol instead of TLS, as tunnels over DTLS are not affected by this issue.|
|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 45527586.|
|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.|
|753347||F5 Access 3.0.4 incorrectly shows http:// for importing client cert instead of https:// as a hint when certificate is imported using. F5 Access only supports HTTPS links for importing client certificates.|
