4 OpenTopic What is BIG-IP Edge Client app for ios? About establishing VPN connections The BIG-IP Edge Client app for ios provides users with two options to establish a VPN tunnel connection. A user can start a tunnel connection explicitly with the Edge Client application, or implicitly through the ios VPN On- Demand functionality. For example, a connection can be configured to automatically trigger whenever a certain domain or hostname pattern is matched. VPN On-Demand considerations: VPN On-Demand configuration is only allowed if the client certificate authentication method is used (legacy logon mode). Username and Password could be used along with the client certificate, but are optional. If a connection is initiated by VPN On-Demand, user intervention is not allowed. For example, the connection will fail if a password is not supplied in the configuration but it's needed for authentication). RSA authentication is also not supported for VPN-On-Demand configuration. If you use VPN On-Demand, only 2 authentication types are supported. In order to add additional credential authentication for this type of configuration, you must perform additional configurations through the app, after you have imported the configuration profile. Running the Network Access Setup Wizard Although optional, you can also set up SSO and ACLsfor your network access. Refer to the BIG-IP Access Policy Manager Adminstrative Guide on AskF5.com for instructions.

6 OpenTopic About access policies for BIG-IP Edge Client app About access policies for BIG-IP Edge Client app In your configuration, you might be required to configure separate access policy branches for the BIG-IP Edge Client app. The BIG-IP Edge Client app does not support client-side checks. There are a number of ways you can configure an access policy to allow a network access connection for ios clients. The following methods can work: Start the access policy with the Client-Side Check Capability check. This provides a branch for clients that do not support client-side checks, including ios devices. Assign authentication and a network access resource to this branch. Use an existing access policy with client-side checks. The ios device will fail to the fallback branch of the first client-side check. Assign authentication and a network access resource to this branch. Create a specific branch for ios clients. You can use an empty action and session variables to identify the ios client. On the branch you identify for ios clients, add authentication and assign a network access resource for ios devices. About the basic access policy example to support BIG-IP Edge Client app You configure your access policy branch to direct mobile device users to have access to the BIG-IP Edge Client app, and provide a Fallback branch to those non-mobile device users.
