BIG-IP Edge Client for Windows

About Component Installer

The Component Installer service enables you to install and upgrade client-side Access Policy Manager (APM) components on Windows-based clients for all kinds of user accounts, regardless of the rights under which the user is working. This component is especially useful for installing and upgrading client-side components when the user has insufficient rights to install or upgrade the components directly.

After you install the Component Installer, it automatically installs and upgrades client-side APM components. It can also update itself. The Component Installer requires that installation or upgrade packages be signed using the F5 Networks certificate or another trusted certificate. By default, F5 Networks signs all components using the F5 Networks certificate.

Downloading and installing the Component Installer

You can pre-install client components for your users who do not have administrative privileges on Windows-based systems.

On the Main screen, click the F5 logo to display the Welcome page.

Scroll to the Downloads area.

In the links for BIG-IP Edge Client Components, click

Component Installer Package for Windows

The MSI installer downloads to your local folder.

On Windows-based clients, install the Component Installer with elevated privileges so that it can install, upgrade, and run APM components that require elevated privileges.

For information about configuring the MSI installer to run with elevated privileges, see the documentation for your operating system.

Overview: Configuring and installing Edge Client for Windows

Users of BIG-IP Edge Client for Windows can connect securely and automatically to your network while roaming using the automatic reconnect, password caching, and location awareness features of Edge Client. You can also enforce Always Connected mode, and configure the list of trusted sites to which to allow access. You can customize the client package and you must download it and make it available to users as hosted content on the BIG-IP system or through another delivery mechanism. Users must install the package, or Component Installer, if available on the client, can install it for them.

About Machine Cert Auth and user privilege

A Machine Cert Auth check requires administrative privilege. The Windows client package associated with a connectivity profile can be configured to include a Machine Certificate Checker Service component. The service can check the machine certificate on a client endpoint even when the user does not have admin privilege. The option to include this component in the package is disabled by default.

About Edge Client location awareness

The BIG-IP Edge Client provides a location-awareness feature. Using location awareness, the client connects automatically only when it is not on a specified network. The administrator specifies the networks that are considered in-network, by adding DNS suffixes to the connectivity profile. With a location-aware client enabled, a user with a corporate laptop can go from a corporate office, with a secured wireless or wired network connection, to an offsite location with a public wireless network connection, and maintain a seamless connection to allowed corporate resources. Network location-awareness can be triggered to run because of various reasons, such as IP changes and network interfaces starting up or shutting down. In reconnect mode, Edge Client might briefly establish a VPN tunnel before the network location-awareness feature can disconnect it. The Edge Client matches DNS suffixes reported by the system API to detect network location.

During a network switch, such as changing Wifi connections, Edge Client with network location-awareness must detect whether the new connection is local or remote. During this detection timeframe, there is a brief amount of time that Edge Client does not block certain external websites and can be reachable during the network switch.

About Edge Client automatic reconnection

BIG-IP Edge Client provides an automatic reconnection feature. This feature attempts to automatically reconnect the client system to corporate network resources whenever the client connection drops or ends prematurely.

About Always Connected mode

BIG-IP Edge Client® provides Always Connected mode. This feature allows you to specify that the client is always connected to the VPN, and allows you to configure the behavior when the client is not connected. You can specify whether the client is connected automatically after Windows logon, and configure exclusion addresses.

check box. Otherwise, clear it.

Virtual servers added to the Trusted sites list with this option remain on the trusted sites list indefinitely. This works with the

User Logon Credentials Access Service

setting (available on the Available Components screen) to provide seamless logon with Edge Client if APM accepts the same credentials that users use to log on to Windows.

To automatically start the Edge Client after the user logs on to Windows, retain selection of the

Auto launch after Windows Logon

check box. Otherwise, clear it.

The existing behavior of

Auto launch after Windows Logon

is to launch Edge Client after the system user logs into Windows and initiates VPN connection automatically. Now, this behavior is changed, and introduced the

Launch in Disconnected State

option which controls automatic VPN connection. If you want the Edge Client to start in the disconnected state, select the

Launch in Disconnected State

option otherwise you can leave the option cleared which is its default state. This feature is only supported for Windows Edge Client. The

Launch in Disconnected State

option is programmatically always set to

False

when Edge Client is deployed with Always Connected mode.

In order to change the default settings, you can add below XML tags in config.f5c file until the BIG-IP 17.1.0 release which will have respective UI settings:

<LAUNCH_IN_DISCONNECTED_STATE>YES</LAUNCH_IN_DISCONNECTED_STATE>

For the Edge Client notifications, when the system is in sleep mode and certain scenarios like VPN connection session expiry or inactivity timeout, Edge Client tries to re-authenticate and prompts the user to enter the credentials. At this point, if the Edge Client is in minimised state it displays

Action Required

user notification for a period of time. A

Maximise Edge Client When Credentials Required

option is introduced to allow the Edge Client login window to maximise itself and prompts for user credentials if required. If you want Edge Client in maximised status while reconnecting or when credentials are required instead of showing Action Required notification, select this option otherwise you can leave the option cleared which is its default behavior. This feature is only supported for Windows Edge Client.

In order to change the default settings, you can add below XML tags in config.f5c file until the BIG-IP 17.1.0 release which will have respective UI settings:

<MAXIMISE_EDGE_CLIENT_WHEN_CREDENTIALS_REQUIRED>YES<MAXIMISE_EDGE_CLIENT_WHEN_CREDENTIALS_REQUIRED>

To customize the

Machine Tunnel Service Config

, select the

Machine Tunnel Service

in the

Available Components

screen from the Customize Windows Client Package window.

The machine tunnel service that supports the maintenance and remote troubleshooting are disabled on a corporate network. If the DNS Suffix matches, the connection is identified as a corporate network, and the client does not attempt to establish a Network Access connection. When the suffixes do not match, the connection is identified as a non-corporate network, and the client attempts to establish a Network Access VPN connection. The machine tunnel service is enabled on a non-corporate network.

If you want to start the Network Location Awareness (NLA) for Machine Tunnel, select the

Enable NLA for Machine Tunnel

option. NLA compares the DNS suffixes present on the system against the administrator configured DNS list and detects whether a connection is corporate or remote. NLA on machine tunnel determines when a client should start a network access connection. This option enables the BIG-IP Edge Client to automatically terminate a VPN session on a corporate network and establish a VPN connection on a remote network.

Click

Download

The screen closes and the package,

BIGIPEdgeClient.exe

, downloads.

The customized package,

BIGIPEdgeClient.exe

, is downloaded to your client. It is available for you to distribute.

Enabling NLA for machine tunnel

The Network Location Awareness (NLA) on machine tunnel determines when a service should establish a Network Access connection with configured APM server.

During a network switch, based on the configured DNS Suffixes, NLA detects whether a network connection is in corporate or non-corporate. If the NLA detects current network connection as corporate network, it enables Machine tunnel service to automatically terminate a Network Access connection and establishes connection back on a non-corporate network.

To enable NLA for machine tunnels using registry editor or push the registry key using group policy, perform the following steps:

Navigate to the

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\F5MachineTunnelService\Parameters

folder.

On the

Edit

menu, click

New

String Value

For String Value, type name as DNSSuffixes.

The type of the registry key is REG_SZ.

Edit the string value and enter the DNS Suffixes that you want to be detected as corporate network. Multiple DNS Suffixes are allowed and they must be separated by a comma without a space.

For example: testdomain.com,test.com

About exclusion list modification

The exclusion addresses are stored as registry keys and not values in the registry in

HKLM\SOFTWARE\WOW6432Node\F5 Networks\RemoteAccess\AlwaysConnected\Exclusions

key. Any values in the key are ignored. You may manually add, edit or remove values under this key using the registry editor or group policy mechanisms. The always-connected service reads those values on start, restart and on network events.

The traffic to the exclusion list is never blocked until the VPN is established, so you can whitelist known identity providers (IdPs) and other sites that are deemed harmless, which improves the usability of locked client mode. After the VPN establishment, the client behaves according to the Network Access resource configuration.

User Interface when OAuth is in progress

Screenshot Edge Client for windows when OAuth is progress — User interface on Windows when OAuth is in progress

The Edge Client User Interface displays the VPN status while the OAuth authentication is in progress.

Authenticating in Browser...: Indicates that the user authentication using the OAuth 2.0 flow is in progress.

User Interface when OAuth is in progress in an Always Connected mode

Edge Client for Windows supports authentication of Native Apps using OpenID Connect specification in an Always connected mode. When OAuth is configured, the end-users are required to authenticate via the OAuth authentication flow.

BIG-IP Edge Client for Windows user interface displays the following additional settings for an OAuth authorization flow in an Always connected mode:

Authenticating in Browser...: Indicates that the user authentication using the OAuth 2.0 flow is in progress.
Click here to retry authentication: This link allows the user to retry authentication manually if the browser window has accidentally closed before the user is authenticated using the OAuth 2.0 flow.

About OIDC Support in Edge Client for Windows

Edge Client for Windows supports authentication of Native Apps using OpenID Connect specification. When OAuth is configured, the end-users are required to authenticate via the OAuth authentication flow. The OAuth 2.0 Authorization Framework describes the method of authorization and defines client, resource server, and identity provider roles. OpenID Connect is built on top of OAuth 2.0 and complements the OAuth 2.0 Authorization framework.

The OIDC support provides consistent authentication experience by enabling two-factor verification and Single Sign-On across Browser and Edge Client. It provides:

Ability to use security keys (Yubikey) as an additional factor of authentication for Edge Client (For example, U2F).

Ability to support password-less authentication through public key registration and authentication.

Single Sign-On for Edge Client and other enterprise apps that share a common IDP.

Beginning BIG-IP version 16.0.0, connectivity profile has optional

OAuth Settings

using which administrators can specify the OIDC authorization server discovery endpoint, Client ID, Scopes, and the Complete Redirection URI.

The OAuth authorization flow for Native Apps using the browser is as follows:

The Edge Client queries the authorization server details from BIG-IP and opens the browser tab with the authorization request.

The authorization endpoint receives the authorization request, authenticates the user, and obtains authorization.

The authorization server then issues an authorization code to the redirect URI.

The Edge Client receives the authorization code and responds with HTTP 302 redirect URI to the

Complete Redirection URI

page on the BIG-IP APM or external web server.

The browser issues a request to the

Complete Redirection URI

page and receives a response from the BIG-IP APM or external web server.

The Edge Client presents the authorization code at the token endpoint, which validates the authorization code and issues the tokens requested.

The Edge Client provides a token in the session authorization request to BIG-IP APM.

The BIG-IP system allows or denies access to the APM session.

When the Edge Client opens the browser for OAuth 2.0 authentication, the client displays the status as

Authenticating in browser...

, indicating that the browser has been opened for the authentication, and the Edge Client is waiting for the authorization code. In case of an error, a window with a BIG-IP logout page and an error message are displayed.

Error Codes in case of OAuth failure

The following error codes might be displayed in the Edge Client logs in case of various failures.

Error Code Hex Value	Description
0xA0040300	OAuth parameters are not configured.
0xA0040301	Access Token was not retrieved.
0xA0040302	Failure to initiate Async OAuth flow in the OAuth library.
0xA0040303	API Client DLL is in the process of performing high level Async OAuth login and/or APM login.

About browser-based connections from Linux, Mac, and Windows clients

For Linux, Mac OS X, and Windows-based systems, the Network Access client component is available for automatic download from the BIG-IP system.

The client component supports secure remote web-based access to the network. It is not the same as the customizable client package that is associated with the connectivity profile.

The first time a remote user starts Network Access, APM® downloads a client component. This client component is designed to be self-installing and self-configuring. If the browser does not meet certain requirements, APM prompts the user to download the client component and install it manually.

About machine tunnels for Windows

Machine Tunnels are a new Desktop Client feature for Windows only. When installed on client machines as a Windows Service, a machine tunnel starts during the machine boot sequence and establishes a VPN connection to the specified APM servers in the background. No user interaction or interactive Windows session is required. This can be used for several different scenarios.

Off-premise or remote initial provisioning

: Machine tunnels can provide connectivity to the corporate datacenter when the user logs in to a corporate laptop for the very first time.

Remote computer maintenance

: IT staff can manage the machine and update the software when the user is not logged in, but the device is on and idle.

Remote troubleshooting

: Support Staff are able to log into a user machine via a secure tunnel.

Remote self-service

: When users forget their passwords, IT staff can use machine tunnels to reset the user passwords.

About machine tunnels and proxy servers

Machine Tunnel works as a privileged, non-interactive process under the LocalSystem account and does not support BIG-IP proxy configuration. Machine Tunnels ignore proxy settings configured in APM network access resource and do not use Local Area Network (LAN) proxy settings on the client, instead, the machine tunnel leaves its per-VPN connection proxy settings empty.

If the network access resource has a network route to 0.0.0.0 and the VPN is connected, Windows tries to apply proxy settings from this connection. Because the connection does not have proxy settings, Windows applies empty proxy settings. If the network access resource does not have a route to 0.0.0.0, Windows does not override the system's proxy settings.

Windows has separate proxy settings for the LAN adapter and each Dial-Up/VPN connection. It uses the proxy settings from the active internet connection which can be either LAN or a Dial-Up/VPN type. When Machine Tunnels are connected with the default full tunnel (0.0.0.0) routing, it is the Active Internet Connection, and Windows uses its empty proxy settings. This results in an effective configuration without proxy regardless of the current LAN settings.

To resolve this issue, split the VPN tunnel resource into multiple subnets. As a result, the machine tunnel VPN client does not create any 0.0.0.0 route.

For example:

1.0.0.0/255.0.0.0

2.0.0.0/254.0.0.0

4.0.0.0/252.0.0.0

8.0.0.0/248.0.0.0

After this routing change, Windows does not consider the machine tunnel VPN as the primary internet connection and uses the LAN proxy settings regardless of the VPN connection status.

About desktop client interactions with machine tunnels

The service establishes a machine tunnel connection on system boot. Once a user logs in to her machine, the user can establish a new VPN connection with the desktop client. A manual client VPN connection overrides the machine tunnel, effectively putting the machine tunnel connection "on hold". The machine tunnel VPN connection pauses until one of the following events occurs:

The user explicitly disconnects from the user-initiated VPN session.

The user logs out of Windows.

The user-initiated VPN session times out.

The user's VPN client is stopped, or the client crashes.

Once one of the interactions above occurs, the machine tunnel connection is resumed.

About creating the machine tunnel installer package

Edge Client 7.1.7 and later supports the ability to create a VPN based on machine credentials with BIG-IP versions 13.1 and above. However, the ability to create a Machine Tunnel installer package through the

Connectivity/VPN

Profiles

Customize Windows Client Package

utility is available for BIG-IP 14.x and above. For BIG-IP 13.x and earlier versions, you must set up the installer package manually and use the Powershell script to build the machine tunnel package.

Overview: Discard non-VPN adapter registration on Network Access DNS server

Microsoft registers the system adapter’s IP and hostname on the DNS Servers (Dynamic address registration) when the

option is enabled for the adapter on Windows. However, users noticed that Microsoft registers the local connection address and PPP adapter (VPN) address on tunnel DNS servers when the

option is enabled on the network adapter and full tunneling is used.

BIG-IP Edge client can intercept DNS traffic and decide whether DNS traffic should be routed to a tunnel DNS server or a local DNS server. To achieve this function, Edge Client uses two components such as service and driver. The driver is TDI-based (Intel platform) and captures DNS events and redirects them to a service that has listeners configured.

The DNS Relay proxy service has been enhanced to drop the registration of local adapters (non-PPP) on DNS Servers configured on Network Access settings.

Administrators can use the APM Variable Assign agent to enable or disable DNS Dynamic Update as per their preference. Following are the possible configuration options:

To disable DNS Dynamic Update, add the following entries to the Variable Assign agent in your policy::

Custom variable:

config.connectivity_resource_network_access./Common/F5Access_NetworkAccess.client.IPv6LAN

Custom expression:

"return {</IPv6LAN><dynamicUpdatePacketFilter0>0</dynamicUpdatePacketFilter0><IPv6LAN>}"

Note:
By default, the configuration option value is set to 0 and the feature to intercept/filter DNS Dynamic Update packet is disabled.

For a deployment that uses a non-secure DNS Dynamic update and would like to filter registration calls, add the following entries to the Variable Assign agent in your policy:

Custom variable:

config.connectivity_resource_network_access./Common/F5Access_NetworkAccess.client.IPv6LAN

Custom expression:

"return {</IPv6LAN><dynamicUpdatePacketFilter0>1</dynamicUpdatePacketFilter0><IPv6LAN>}"

Note:
System generated DNS Update packets are modified and sent to Network Access DNS server.

For a deployment that uses secured DNS Dynamic update and would like to filter registration calls., add the following entries to the Variable Assign agent in your policy:

Custom variable:

config.connectivity_resource_network_access./Common/<F5Access_NetworkAccess>.client.IPv6LAN

Custom expression:

"return {</IPv6LAN><dynamicUpdatePacketFilter0>2</dynamicUpdatePacketFilter0><IPv6LAN>}"

Note:
System generated DNS Update packets are dropped and a new secured record is created by proxy code and sent to the DNS server.

For any value other than 0, 1, 2, the DNS relay proxy sets to 0.

Configuring APM Variable Assign agent to enable or disable DNS Dynamic Update

Administrators can use the APM Variable Assign agent to enable or disable the DNS Dynamic Update. Follow the steps to configure the dynamicUpdatePacketFilter value from variable assignment in the BIG-IP.
