Access Policy Manager configuration tips

The following table provides tips for setting up F5 Access for devices.

Feature Information
Proxy servers Public and private-side proxy servers are not currently supported.
Client endpoint checks Client end-point checks are not currently supported.
Require device authentication For devices with Android 6.0 or later, F5 Access can require device authentication with one of the device locking methods, including biometric authentication, a PIN, a pattern, or a passphrase. To enable device authentication for F5 Access, in the Connectivity Profile under Android Edge Client, enable the options Allow Password Caching and Require Device Authentication.

This setting has no effect on devices with a pre-Android 6.0 OS. On such devices, even with this setting configured on the server, users must enter a password for each connection.

Password caching policy
  • In the Connectivity profile, you can configure password caching by enabling the setting Allow Password Caching. When this setting is enabled, after a successful logon the submitted credentials are cached.
  • Specify a Save Password Method.
    • If you select disk, an encrypted password is cached on the device with no expiration time.
    • If you select memory, an encrypted password is cached on the device for the time specified in the Password Cache Expiration (minutes) field.
  • Credentials are not cleared if the user disconnects or restarts the device.
  • If credentials are cached and the Save Password Method is memory, then credentials are cached until one of the following events occurs:
    • The specified credential cache duration expires.
    • The server address of the configuration within the application changes.
    • The username of the configuration within the application changes.
    • The F5Access user switches between configurations.
  • To require the user to authenticate on the device before unlocking the cached credentials, select Require Device Authentication.
Client certificates Client certificate authentication is supported in Web Logon mode with or without a password. In standard logon mode, certificates are supported, but a password is required. A password (including an empty password) can be saved in the configuration.

About starting the client from a URL scheme

You can start F5 Access connections for users from a URL. You can then provide these URLs to users, so they can start the VPN connection without having to manually start the application. If there is already an active connection, a prompt appears to warn the user that the existing connection must be stopped before the new connection can start. The connection uses a client certificate if it is specified in the existing configuration.

URL connections use the following parameters. This is an example, you must provide your own parameters and values.

f5access://{start|stop}?[parameter1=value1&parameter2=value2...]
Note: Special characters in parameters must be URL-encoded.

You can start an alternate light client with no client branding, using the following parameters.

f5access-lite://{start|stop}?[parameter1=value1&parameter2=value2...]

The syntax to start a connection from a URL follows.

start
Starts a connection. The start command requires either the name or server parameter to be present in the URL. If the name parameter is specified, then F5 Access looks for the name in the list of existing configuration entries. If the server parameter is specified, then the name parameter is set to the same value as the server parameter. A new configuration is created if a configuration with that name does not exist. If the specified configuration already exists, the other parameters specified in the URL are merged with the existing configuration. The result of this merged configuration is used only for the current, active connection, and does not persist. If a name is specified with other parameters, such as server, username, or password, those parameters override what is specified in the configuration.
sid
A parameter used to specify the session ID with which to start the connection. When the parameter sid is provided, the username and password parameters are ignored, and no additional authentication occurs.
username
A parameter used to specify the user name with which to start the connection. When the username is specified without a password, then an authentication prompt is displayed.
password
A parameter used to specify the password with which to start the connection. When the password parameter is specified, it is used as a one-time password and not saved in the configuration.
postlaunch_url
A parameter used to specify the URL that starts after the connection starts.
logon_mode
An optional parameter that specifies whether the logon mode is the standard logon (native) or web logon (web). The default logon mode is native.
hide_ui_when_connected
An optional parameter to minimize the F5 Access user interface for users when a connection has been established successfully. The value can be either yes or no. The default value is no.
fips_mode
An optional parameter to enable a connection compatible with FIPS 140-2 operation mode. The value can be either yes or no. The default value is no. The mode fips_mode=yes cannot be used with logon_mode=web.
allowed_apps and disallowed_apps
Allows or prevents a list of applications access to the VPN. Only one option can be used at a given time.
securid_sn
An optional parameter to present the software token serial number for RSA SecurID authentication.
allow_bypass
An optional parameter to allow apps to bypass VPN connection. The value can be either yes or no. The default value is no.

About defining a server from a URL

You can add BIG-IP® server definitions to F5 Access from a URL. You can provide these URLs to users, so they can create and/or start VPN connections without having to manually start the application.

Use the following URL and parameters to create a server:

f5access://create?server=server_address[&parameter1=value1&parameter2=value2...]
Note: Special characters in parameters must be URL-encoded.

The syntax to define a server from a URL follows.

server
The server address is either a DNS name or an IP address.
name
An optional description of the server.
username
An optional parameter used to specify the user name with which to start the connection. When the username is specified without a password, then an authentication prompt is displayed. If no username is specified during server creation, the user is prompted for it at session initiation, if required.
password
An optional parameter used to specify the password with which to start the server connection. When the password parameter is specified, it is used as a one-time password and not saved in the configuration.
cert_url
The URL for downloading a client certificate in .P12 format.
cert_keychain_alias
