Introduction

The Cisco AnyConnect Secure Mobility client for Apple iOS provides seamless and secure remote access to enterprise networks. The client allows any installed application to communicate as though connected directly to the enterprise network.

The App Store provides installation app and all updates. The Cisco Adaptive Security Appliance (ASA) is the secure gateway that admits access to the VPN, but it does not support updates of AnyConnect for Apple iOS.

AnyConnect for Apple iOS is similar to AnyConnect for Windows, Mac OS X, and Linux. Your organization may provide additional documentation on using AnyConnect on Apple iOS.

New Features and Fixes Since AnyConnect 2.4.2

This release features the following enhancements and fixes:

iPad support (Apple iOS 4.2 required).

Apple iOS 4.2 as well as 4.1 support for the iPhone.

Clear Profile Data—Lets you remove the hosts and policy settings that make up the AnyConnect profile imported from an ASA. To access, tap Diagnostics. If you reconnect to the domain, IP address, or Group URL of the same ASA, it reloads the profile and re-enforces the security policies.

Application URI Handling—Lets other applications add VPN connection entries to the AnyConnect configuration, establish VPN connections, and disconnect from a VPN. Your system administrator has the option to provide you with access to this feature.

Certificate Deletion— Let you use AnyConnect to delete any certificate imported via AnyConnect SCEP. To do so, swipe right on the Select Certificate window, the tap Delete. You cannot use AnyConnect to delete certificates that were imported via IPCU or any source outside the AnyConnect application.

Cisco Profile Deletion—You can use AnyConnect to delete the locally hosted Cisco profile. This feature allows the clean removal of imported hosts and policy settings imported from the ASA. If you reconnect to the domain name, IP address, or Group URL of the same ASA, it reloads the profile and re-enforces the security policies.

Expanded Diagnostics and Logging—Enhanced the tools in the Diagnostics window formerly named "Troubleshooting." These enhancements include:

Improvements to the usability of the log message view.

Removal of unnecessary log messages.

Separation of Application and Service level logs.

Device information added to the new email message that AnyConnect opens when you tap E-mail Logs.

Improved severity levels of log messages.

Improved error reporting when connecting to HTTPS servers that are not secure gateways.

Link in the About window that opens an updated iPhone or iPad user guide, depending on the device.

Fixed crash when toggling Wi-Fi on or off.

Fixes to certain situations where the tunnel would be disconnected when in a reconnecting state.

Support for IPv6 resources accessed over the VPN connection.

Bandwidth graphs for the iPad.

High contrast theme alternative to the Cisco default theme. Access the Apple Settings and tap AnyConnect, then tap the theme you want.

What You Need Before You Can Set Up AnyConnect

You must obtain one or more of the following from your system administrator, depending on your network requirements, before you can set up AnyConnect to establish a VPN session:

Server Address—Domain name, IP address, or Group URL of the Cisco Adaptive Security Appliance to be used as the VPN secure gateway.

Username and password—Credentials need to access the VPN.

Alternatively, your system administrator may supply a link on your corporate network that you can tap to add the required connection entries to your iPad.

The Apple iOS Connect On Demand feature, if used, supports the automation of a VPN connection as needed by the applications on your device. However, you must install a digital certificate on the device first. The certificate must be one that the secure gateway accepts. Your system administrator determines which certificate the secure gateway accepts for its respective group URLs.

You can use the following methods to install one or more certificates:

Use an Apple iOS device configuration profile (installed via the iPhone Configuration Utility).

Follow instructions provided by your system administrator to use AnyConnect to import a certificate.

You must specify which certificate you want to use for each VPN connection entry for which you will use a certificate. If you are not using any other form of authentication, it is best to use a Group URL supplied by your system administrator.

Installation

You can install the Cisco AnyConnect Secure Mobility client for Apple iOS from the Apple App Store, as follows:


Step 1 Open the App Store.

Step 2 Select Search.

Step 3 In the Search Box, enter anyconnect and tap cisco anyconnect in the Suggestions list.

Step 4 Tap AnyConnect.

Step 5 Tap Free, then INSTALL APP.

Step 6 Select Install.


Getting Started

To get started,


Step 1 Swipe to the right of the iPad home window, then tap the Cisco AnyConnect icon.

A confirmation window opens the first time you start AnyConnect on the device.

Step 2 Tap OK.

AnyConnect shows the VPN connection status in the AnyConnect home window.

Before establishing your first VPN connection, follow the instructions below to add a VPN connection entry.


Adding a VPN Connection Entry

These instructions may be unnecessary if your system administrator supplied you with a webpage link to tap to add connection entries to the AnyConnect configuration.

Before attempting to establish a VPN connection, add a VPN connection entry to identify the Cisco secure gateway, as follows:


Step 1 Tap Add VPN Connection in the AnyConnect home window.

The Add VPN Connection window shows the VPN connection parameters.

The Selected Certificate and Connect on Demand options appear only if you tap ON next to Use Certificates.

AnyConnect dims the Save button until you complete all the required fields.

If you want to return to the AnyConnect home window without saving changes, tap Cancel.

Step 2 Tap a parameter field to assign a value.

Use the on-screen keyboard to enter a value.

Step 3 Complete the fields, as follows:

Description—Enter a unique name for the connection entry to appear in the connection list of the AnyConnect home window. We recommend using a maximum of 24 characters to ensure they fit in the connection list. You can use any letters, spaces, numbers, or symbols on the keyboard. AnyConnect retains the letters in the upper- or lower-case letters you specify. For example,

Example 1
 
   

Server Address—Enter the domain name, IP address, or Group URL of the Cisco Adaptive Security Appliance with which to connect. For example,

vpn.example.com
 
   

Network Roaming—(Optional) Determines whether to limit the time it takes to reconnect after the device wakes up or after a change to the connection type (e.g., EDGE, 3G, Wi-Fi).


Note This parameter does not affect data roaming or the use of multiple mobile service providers.


Tap this switch, as follows:

ON—(Default) This option optimizes VPN access. If AnyConnect loses a connection, it tries to establish a new one until it succeeds. This setting lets applications rely on a sustained connection to the VPN. AnyConnect does not impose a limit on the time it takes to reconnect.

OFF—This option optimizes battery life. If AnyConnect loses a connection, it tries to establish a new one for 20 seconds and then stops trying. You must then start a new VPN connection if one is necessary.

Use Certificates(Optional, depending on VPN requirements.) Your system administrator will provide you with instructions for installing a certificate if one is necessary to establish a VPN session. AnyConnect detects the installation of one or more certificates on the device. The absence of a certificate on the device prevents you from changing this setting. If a certificate is installed on the device, you can tap this switch as follows:

ON—uses a certificate when connecting to a security appliance that requires a certificate. This option requires at least one client certificate to be installed. This option enhances network security access, and is required for Connect on Demand.

OFF—uses another method to authenticate, such as logging in manually when establishing a VPN connection with a security appliance.

Selected Certificate—(Displayed only if Use Certificates is set to ON.) Tap to choose the certificate to be used for authentication when connecting to the ASA. The Select Certificate windows shows the Certificate Name, Issuer, and Expiration Date of each certificate installed on the device.

Step 4 (Optional) Tap the certificate required for access to the VPN. AnyConnect reads the values embedded in the certificate and displays them in the Select Certificate Details window. Tap Select Certificate at the top of this window.

Step 5 (Optional) Complete the remaining parameters, as follows:

Connect on Demand—(Displayed only if Use Certificates is set to ON.) Tap this switch, as follows:

ON—Lets applications start a VPN connection when they attempt to access a domain specified in the domain list below. This option requires a certificate.

OFF—Prevents applications from starting a VPN connection. Using this option is the only way to prevent an application that makes a DNS request from potentially triggering a VPN connection.

Domain List—(Displayed only if Connect on Demand is set to ON.) Lists the domains for which Connect on Demand match rules apply. For instructions, see the next section.

Step 6 (Optional) Tap Save to retain the connection values.

AnyConnect closes the Add VPN Connection window and adds the entry to the home window.


Setting Up Connect-On-Demand Rules

The Apple iOS Connect On Demand feature lets an application such as Safari initiate a VPN connection. AnyConnect evaluates the domain requested by an application against the strings in the domain lists within the active connection entry—the entry with the check mark next to it.

Never Connect—AnyConnect evaluates domain requests for a match against the contents of this list first. If a string in this list matches the domain, Apple iOS ignores the domain request. This list lets you exclude certain resources. For example, you might not want an automatic VPN connection over a public facing Web server. An example value is www.example.com.


Note If you or the user enable Connect On Demand, AnyConnect adds the server address in the VPN configuration to the Never Connect list to prevent VPN connections from starting when you use a web browser to connect to a secure gateway. Leaving the rule in place does not have an adverse effect on Connect on Demand.


Always Connect—AnyConnect evaluates domain requests for a match against the contents of this list next. If a string in this list matches the domain, Apple iOS attempts to establish a VPN connection. The most common use case for this list is to obtain brief access to internal resources. An example value list is email.example.com.

Connect if Needed—AnyConnect evaluates a domain request for a match against this list if a DNS error occurred. If a string in this list matches the domain, Apple iOS attempts to establish a VPN connection. The most common use case for this list is to obtain brief access to an internal resource that is not accessible in a LAN within the corporate network. An example value is intranet.example.com.

Apple IOS establishes a VPN connection on behalf of an application only if all of the following are true:

A VPN connection is not already established.

An application compatible with the Apple iOS Connect on Demand framework requests a domain.

The connection entry is configured to use a valid certificate.

Connect on Demand is enabled in the connection entry.

AnyConnect fails to match a string in the Never Connect list to the domain request.

Either of the following is true:

AnyConnect matches a string in the Always Connect list to the domain request.

A DNS lookup failed and AnyConnect matches a string in the Connect if Needed list to the domain request.

The domain lists specify the Connect on-Demand rules. These rules support only domain names, not IP addresses. The domain names specified within the rules may be partial or whole domain strings. Use a comma to separate list entries. AnyConnect is flexible about the domain name format of each list entry, as follows:

Match
Instruction
Example Entry
Example Matches
Example Match Failures

Exact prefix and domain name only.

Enter the prefix, dot, and domain name.

email.example.com

email.example.com

www.example.com

email.1example.com

email.example1.com

email.example.org

Any prefix with the exact domain name. The leading dot prevents connections to hosts ending with *example.com, such as notexample.com.

Enter a dot followed by the domain name to be matched.

.example.org

anytext.example.org

anytext.example.com

anytext.1example.org

anytext.example1.org

Any domain name ending with the text you specify.

Enter the end of the domain name to be matched.

example.net

anytext.anytext-example.net

anytext.example.net

anytext.example1.net

anytext.example.com


AnyConnect does not limit the maximum number of domains in a list.

To open a VPN connection when an application requests access to one or more specific domains:


Step 1 Open the AnyConnect home window.

Step 2 Tap the icon to the right of the connection entry or tap Add VPN Connection.

Step 3 Enter a name for the VPN connection into the Description field.

Step 4 Enter the domain name, IP address, or Group URL of the Cisco Adaptive Security Appliance provided by your system administrator.

Step 5 Tap ON next to Use Certificates.

Step 6 Select the certificate required for the connection as provided by your system administrator and tap Add VPN Connect.

AnyConnect returns to the Add VPN Connection window.

Step 7 Tap ON next to Connect On Demand.

Step 8 Tap Domain List.

The Domains window shows the domain lists.

Step 9 Do either of the following:

Tap Add Domain to add a domain string to the list shown. The Domains window adds a row to the list and displays an on-screen keyboard for you to enter the domain string.

Tap Edit at the top of the window to add, edit, or delete domain strings.

This window lets you:

Add a domain name to a list. To do so, tap Add Domain. AnyConnect adds a blank row to the list and displays an on-screen keyboard for you to add the list entry.

Move a domain name from one list to another. To do so, touch the triple-bar to the right of the domain entry and drag it to the area below the title of the destination list.

Delete—Tap the red circle to the left of the domain name, then tap Delete to the right of the domain.

Tap Save.


Modifying a VPN Connection Entry

You might need to change a VPN connection entry to correct a configuration error or comply with an IT policy change. To do so:


Step 1 Open the AnyConnect home window.

Step 2 Tap the icon to the right of the VPN connection entry.

AnyConnect displays the VPN connection parameters.

Step 3 Tap a parameter to change a value.

Step 4 Use the on-screen keyboard to enter the new value.


Note You cannot fully edit connections that have been imported from an AnyConnect VPN Profile or the iPhone Configuration Utility mobileconfig.


For parameter instructions, use the online help or go to Adding a VPN Connection Entry.

Step 5 Tap Save.

AnyConnect closes the connection parameter window.


Deleting a Connection Entry

Tip Tap the link to use Safari to open the latest updated version of this guide. Use it as a resource if you need to use these instructions at a later time.


Responding to "Another Application has requested that AnyConnect...Do you want to allow this?"

To protect your device, AnyConnect informs you when another application attempts to generate a connection profile, establish a VPN connection, or disconnect from a VPN, and prompts you whether it is OK. For example,

The Connect on Demand feature permits these features; however, to protect your device and data, please ask your system administrator whether to tap OK to approve of these types of prompts:

Create—"Another application has requested that AnyConnect create a new connection to `host'. Do you want to allow this?"

Connect—"Another application has requested that AnyConnect connect to `host'. Do you want to allow this?"

Connect—"Another application has requested that AnyConnect disconnect the current connection. Do you want to allow this?"

Troubleshooting

This section describes solutions to common problems. If after trying these solutions problems still persist, contact your organization's IT support department.

I cannot edit/delete some profiles.

Your system administrator set a policy that affects host entries imported into your AnyConnect profile. To delete these profiles, tap Diagnostics and tap Clear Profile Data.

Errors while trying to save or edit configuration.

A known issue with the operating system is the cause. Apple is working to resolve it. As a workaround, try restarting the application.

Connection time-outs and unresolved hosts.

Internet connectivity issues, a low cell signal level, or congested network resource often cause time-outs and unresolved host errors. If a LAN is within reach, try using your device Settings app to establish a connection with the LAN first. Retrying multiple times in response to time-outs often results in success.

VPN connection is not re-established when the device wakes from sleep.

Enable Network Roaming in the VPN connection entry. If enabling network roaming does not resolve the issue, check your EDGE, 3G, or Wi-Fi connection.


Note This issue could be expected behavior depending on how your organization has configured the VPN.


Certificate-based authentication does not work.

Check the validity and expiration of the certificate if you succeeded with it before. Check with your system administrator to make sure you are using the appropriate certificate for the connection.

The Apple iOS Connect On Demand feature is not working or connecting unexpectedly.

Ensure the connection does not have a conflicting rule in the Never Connect list. If a Connect If Needed rule exists for the connection, try replacing it with an Always Connect rule.

AnyConnect failed to establish a connection but no error message was displayed.

Messages can be displayed only when the AnyConnect application is open.

A profile called Cisco AnyConnect exists that cannot be deleted.

Try restarting the application.

When I remove the AnyConnect application, VPN configurations still appear in the Apple iOS VPN settings.

To delete these profiles, reinstall AnyConnect, tap Diagnostics, and tap Clear Profile Data.

Removing AnyConnect

To remove AnyConnect from the device,


Step 1 Open AnyConnect, tap Diagnostics, and tap Clear Profile Data to remove it from the Apple iOS VPN settings.

Step 2 Press the menu button to go to the iPad home window.

Step 3 If you placed AnyConnect in a folder, open the folder.

Step 4 Tap and hold the AnyConnect icon until a delete (X) icon appears above it.

Step 5 Tap the delete icon.
