Features and Enhancements

Implemented IP filtering engine on macOS

Previously, Mac users were able to access both internal resources and unsecured local LAN resources at the same time, leading to potential DLP issues. IP Filtering Engine is implemented for macOS which ensures that the traffic destined to the VPN does not leak to the user's LAN and it prevents access from the user's LAN to the VPN (when user's device acts as a router). 

Fixes

The following issues have been fixed in this release.

ID Number Description
1235413-1 Fixed the issue where Edge Client was becoming unresponsive in initializing when 'HTTP' was used in OS proxy setting.
1398321-1 Fixed the issue where Split Tunnel Route table was not restoring properly while switching VPN.
1394877-1 Fixed the issue where DTLS connection was dropped frequently in Windows Edge Client.
1380085-1 Fixed the issue where the configuration data corrupted pop-up was showing for the first time after macOS upgrade.
1352397-4

Known issues

The following are known issues in this release.

ID Number Description
1072901 The Windows logon integration does not work with TLS 1.3 on windows 10 and Windows 11.

Workaround: Enable other versions of TLS to allow Windows Logon client to fallback to an older version of TLS protocol.

1079621 When the application is moved to the trash, the respective application F5 EPI or F5 VPN directory is getting deleted from the following path:

/Applications/F5 Endpoint Inspector.app/Contents/Resources/

Whereas, the respective application specific (F5 EPI or F5 VPN) folder is not getting deleted from the following path:

/Users/<username>/Library/Applications Support/F5 EPI

The plist file of the respective application is not deleted from the following path:

/Users/<username>/Library/Launchagents/

Workaround:
 
If you are running MacOS Version 12.2 or later
  1. Upgrade to the latest build and verify the applications are recent:

    /Applications/F5\ VPN.app

    /Applications/F5\ Endpoint\ Inspector.app

  2. Delete the following LaunchAgents:

    ~/Library/LaunchAgents/com.f5.f5epihelper.plist

    ~/Library/LaunchAgents/com.f5.f5epihelper.plist

  3. Delete the following python scripts:

    ~/Library/Application\ Support/F5\ VPN/uninstall.py

    ~/Library/Application\ Support/F5\ EPI/uninstall.py

  4. Reboot the device to remove the Launch agents in memory.
1082821 When trying to establish a VPN connection using a browser, it does not work with TLS 1.3 on all versions of macOS.

Workaround: Enable other versions of TLS to allow the browser to fallback to any other versions of TLS protocol.

1082825 When trying to establish a VPN connection using a browser, it does not work with TLS 1.3 on Linux.

Workaround: Enable other versions of TLS to allow the browser to fallback to any other versions of TLS protocol.

1082909 When trying to establish a VPN connection, it does not work with TLS 1.3 on Windows 11.

Workaround: Enable other versions of TLS to allow APM client to fallback to any other versions of TLS protocol.

1083397 Installation of the Edge Client versions prior to 7.2.2 may be successful on the ARM64-based Windows 10 and Windows 11 but fails to establish the VPN connection.

Workaround: Uninstall the prior versions of Edge Client 7.2.2 and install the ARM64-supported Edge Client version using the MSI installer package.

1084369 Optimized tunnels are not supported on ARM64-based Windows 10 and Windows 11 systems. When Optimized tunnels are used, the tunnel connection fails without user notification.

Workaround: In some cases, use a static app tunnel to establish a tunnel connection.

1194381 An intermittent issue is observed when Edge Client on Windows fails to reconnect if the LAN cable is unplugged when the system is asleep.

Workaround 1:

Add the Virtual Server FQDN to the stonewall exclusion list on BIG-IP.

Workaround 2:

The LAN cable should be unplugged from the Windows system prior to hibernation if the user does not want to continue with LAN connectivity after coming out of hibernation.

Workaround 3:

If step 1 is missed or skipped, and faces the Edge Client reconnect issue after coming out of hibernation then the Ethernet cable must be plugged into the Ethernet port on the Windows system. If there is no Ethernet cable, restart the Edge Client application.

1239253 Web F5 VPN will not be launched if certain versions of Ubuntu on ARM64 do not have the /lib/aarch64-linux-gnu/libpcre16.so.3 library installed.

Workaround:

Users who want to use web F5 VPN on certain versions of Ubuntu running on ARM64 which do not have /lib/aarch64-linux-gnu/libpcre16.so.3 should install libpcre16-3 using one of the following commands.

sudo apt install libpcre16-3

or

sudo apt-get install libpcre16-3

1295133 Edge Client users are prompted to install the Endpoint Inspection (EPI) helper applications on macOS 13.3.

Workaround:

Preinstalling the latest EPI helper application would resolve the issue.

For more information on the deployment process, refer to the Install the latest Edge Client on MacOS end devices section of the K000133476 article.

For more details on the user experience changes, refer to the K000133622 article.

1324053-1 Users experience a one-time issue on Windows and MacOS as Edge Client configuration settings which were defined in the client.f5c are overwritten with the settings defined in the config.f5c when the auto-upgrade is enabled. This issue would not be seen when users upgrade from APM Clients 7.2.4.3 version to the future versions.

 

Workaround:

Administrators can define the desired configuration, especially the APM virtual server list in the config.f5c before the upgrade so that the Edge Client Installer copies the settings to the client.f5c file.

Generally, the config.f5c file is available in the following directory path:

Windows: C:\ProgramData\F5 Networks\Secure Access Client or C:\Program Files (x86)\F5 VPN

MacOS: /Library/Application Support/F5Networks

1505789 Edge Client fails to build the VPN connection with an error message as "Network is vulnerable".
