Features and enhancements
- APM VPN proxy support on Android
With this release, proxy support is added for F5 Access Android client to make sure that traffic flows through the back-end proxy server. Administrator can configure the proxy settings on the BIG-IP. The configured proxy settings are shared with the client through the existing secured channel (URL) and applied the settings to the VPN framework. When the VPN connection is established, the traffic flows through the tunnel to the proxy server enhances the security while providing access only to the authorized websites.
If the existing Network Access proxy configuration is applied to all platforms, when users upgrade to F5 Access Android 3.0.9 version, they may see the traffic from Android clients routing through the proxy without any changes to the existing APM configuration. If you would like to apply the proxy configuration only for Android clients then create a separate Network Access configuration with the required proxy configuration as specified above and attach it to the access policy that applies to only Android clients.
F5 Access application is limited by what the Google VPN framework supports. Supported proxy related settings are either HTTP or HTTPS proxies using the pac file. When the proxy is applied through the VPN, it has been noticed that proxy.pac is applied system wide. Modify the pac file in case the proxy needs to be specific to spilt tunnel scope.
For more information, refer to the K08508310 article.
Note: Few applications may ignore the configured proxy settings. In such cases, contact the support team of the respective application for assistance.
The following are known issues in this release:
Known issues in F5 Access
|When F5 Access uses split tunneling for traffic, after establishing a VPN connection, all DNS queries are sent to the VPN-configured enterprise DNS server.
|F5 Access does not change to the Reconnecting state if the GTM server is down. Load balancing with GTM does not work.
|The web logon screen might disappear when you send F5 Access to the background after entering an RSA SecurID software token PIN.
Downloading a client certificate or token from an HTTP URL on Android 9 fails. This is because of the improved security imposed by Android.
Workaround: Use the HTTPS URL with a trusted CA to download the client certificate or token.
VPN connection fails to establish with FIPS mode enabled on certain devices.
Workaround: Disable the FIPS mode before establishing a VPN connection.
|F5 Access running on Android 10 does not send the device's IMEI number to the APM. If MDM is configured to have a dependency on the IMEI number, it would fail.
Workaround: Use MDM assigned unique device ID for identifying devices.
|F5 Access running on Android 10 sends incorrect wifi MAC address to the APM. Therefore, if MDM uses this address to query device compliance status from Intune, the query fails.
Workaround: Use MDM assigned unique device ID for identifying devices.
Known Issues in Third-Party Software
|VPN connections repeatedly fail with the Thursby smart-card reader if you do not enter the smart card unlock PIN before the 30-second timeout has expired. This is caused by a known issue in Thursby SubRosa app.
Workaround: Force stop the SubRosa app, or reboot the device.
|F5 Access fails to read smart cards using Thursby smart card reader when running within Android for Work profile.
|When Always-On VPN Mode is enabled, a VPN connection is established, and a Network Access resource is configured to use split tunneling, resources from the split tunneling space can be successfully accessed using the managed application, but the managed application cannot access all resources outside of the split tunneling space.
|In Android 7.0 RC4, ciphers and SSLv3 are disabled for security reasons. AES ciphers must be enabled in the RSA Authentication Manager configuration for Dynamic Seed Provisioning (CT-KIP) to work on Android 7.0. For more details, see https://community.rsa.com/docs/DOC-45530.
Workaround: Follow the steps in the linked article to enable non-RC4 cipher suites.
|In most cases, when an Always-On VPN is disabled by the DPM (Device Policy Manager), the F5 Access VPN revokes if it is currently connected. In some corner cases, if F5 Access is not connected when, for example, the DPM enables Always-On VPN, but the connection doesn't start because of a misconfiguration, and the DPM then disables Always-On VPN, F5 Access won't be notified, and may continue to attempt to reconnect until the device is rebooted.
|If Always-On VPN mode is enabled for F5 Access by an MDM, and a force stop is done, F5 Access goes into the Disconnected state, and the user loses internet access through managed apps. F5 Access does not reestablish the VPN connection automatically.
Workaround: Restart the device to reestablish Always-On VPN mode. Another workaround is to disallow force stops in the MDM configuration, using DISALLOW_APPS_CONTROL.
|On some devices with Android 4.x, F5 Access Home screen icons might not get updated, and continue to show the older Edge Client icon. This is caused by Android issue 42921: https://code.google.com/p/android/issues/detail?id=42921
|On certain Android devices, F5 Access displays two icons in the notification area when connected to VPN. This behavior is by design.
|The RSA SecurID software token PIN setup might timeout if you do not provide a new PIN within the RSA SecurID token interval.
|Samsung devices provide a way to disconnect Always-On VPN through notification. As a result, when you terminate always-on VPN, the system revokes VPN permission for F5 Access. This prevents F5 Access from establishing a VPN connection.
Workaround: Uninstall and reinstall the F5 Access.
|There is no API to get the Chrome OS version when F5 Access for Android is running on Chrome OS. This being a Chrome issue is currently reported to Google and tracked through 881005.
|Always-On VPN can be turned off from the Chrome OS network settings. This action should not be allowed as it defeats the purpose of Always-On VPN. This issue is currently reported to Google and tracked through 881107.
Workaround: Do not turn off Always-On VPN in the Chrome OS network settings.
|When adding a new VPN configuration through the Chrome OS settings, the F5 Access home screen is launched instead of the Add Configuration screen.
Workaround: Navigate to the Add Configuration screen and add a new configuration. This issue is currently reported to Google and tracked through 881123.
|For F5 Access for Android on Chrome OS, the per-app VPN's feature to allow/disallow apps to bypass VPN connection is reserved. As a result, the disallowed apps pass through the VPN tunnel and allowed apps are blocked through the VPN tunnel. This issue is currently reported to Google and tracked through 883529.
