AnyConnect can falsely assume it is in a captive portal in these situations. If AnyConnect attempts to contact an ASA with a certificate that contains an incorrect server name (CN), then the AnyConnect client will think it is in a captive portal environment. In order to prevent this issue, make sure that the ASA certificate is properly configured.

Primer

This guide will assist with the installation of the Cisco AnyConnect VPN client for Windows (Vista, 7, 8.1 and 10).

Installation

You need administrator level account access to install this software. When prompted with Windows UAC (User Access Control) you need to allow to install this software.

1. Download the VPN installer from MIT's download page, Cisco AnyConnect VPN Client for Windows. Note:MIT certificates required.
   
2. Find and double click the downloaded file named 'anyconnect-win-4.5.XXXXXX.exe', where XXXXXX is the sub-version number of the installer.
   
3. On the following screen titled 'Welcome to the Cisco AnyConnect Secure Mobility Client Setup Wizard', click Next.
   
4. When presented with the software license agreement, click I accept on the slide-down menu and click Next.
   
5. Click Install when prompted (Note: the user must be an administrator of the machine to install).
   Note: You may be warned the program comes from an unknown publisher and asked to confirm that you want to allow it to make changes to your computer. Click Yes to continue.
   
6. When installer begins installation you will see
   
7. Click Finish when prompted to complete installation.
   

   Connect

8. Launch Cisco AnyConnect.
9. Enter the address of the MIT Cisco VPN:
   • Duo (two-factor authentication) required users must use: vpn.mit.edu/duo.
   • Non-Duo (single-factor authentication): vpn.mit.edu
10. Click Connect.
    
11. When prompted, enter your MIT username and password.
12. For Duo users, in the field labeled 'Second Password' you can enter one of the following options:
    1. push - Duo will send a push notification to your registered cell phone with the Duo Security mobile app installed
    2. push2 - Duo will send a push notification to your _second registered device with the Duo Security mobile app installed_
    3. sms - Duo will send anSMSto your registered cell phone; then enter that as your second password (you will fill out the login info twice with this method, first to get the sms code, then to enter it)
    4. phone - Duo will call your registered cell phone
    5. phone2 - Duo will call your second registered cell phone
    6. The one time code generated by your hardware token or the Duo Security mobile app (the code changes ever 60 seconds)
       In this example, we've entered 'push' in the 'Second Password' field.
       Sometimes methods with lag time, like Call, will time out before allowing you to complete Duo Authentication. SMS and one time codes generated by your hardware token (yubikey) or the Duo Security mobile app are the fastest methods and can help you avoid time-out issues.
       

       'How to call different devices' If you have multiple devices that can use the same method, for instance two mobile phones or two phones that can receive phone calls, you can reference them by different numbers. For instance, to call the top device on your managed devices page (http://duo.mit.edu), you can use 'phone' (for the default) or 'phone1' to call the second phone, you can use 'phone2'.

       
       

13. In this example, you will receive a push notification on your cell phone. Click Approve.
    
14. Cisco AnyConnect should now present you with the MIT VPN banner and the VPN connection will complete.

Introduction

This document describes the Cisco AnyConnect Mobility Client captive portal detection feature and the requirements for it to function correctly. Many wireless hotspots at hotels, restaurants, airports, and other public places use captive portals in order to block user access to the Internet. They redirect HTTP requests to their own websites that require users to enter their credentials or acknowledge terms and conditions of the hotspot host.

Prerequisites

Requirements

Cisco recommends that you have knowledge of the Cisco AnyConnect Secure Mobility Client. Canary email.

Components Used

The information in this document is based on these software versions:

• AnyConnect Version 3.1.04072
• Cisco Adaptive Security Appliance (ASA) Version 9.1.2

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Background Information

Many facilities that offer Wi-Fi and wired access, such as airports, coffee shops, and hotels, require users to pay before they obtain access, agree to abide by an acceptable use policy, or both. These facilities use a technique called captive portal in order to prevent applications from connecting until users open a browser and accept the conditions for access.

Captive Portal Remediation Requirements

Support for both captive portal detection and remediation requires one of these licenses:

• AnyConnect Premium (Secure Sockets Layer (SSL) VPN Edition)
• Cisco AnyConnect Secure Mobility

You can use a Cisco AnyConnect Secure Mobility license in order to provide support for captive portal detection and remediation in combination with either an AnyConnect Essentials or an AnyConnect Premium license.

Note: Captive portal detection and remediation is supported on the Microsoft Windows and Macintosh OS X operating systems supported by the release of AnyConnect that is in use.

Captive Portal Hotspot Detection

AnyConnect displays the Unable to contact VPN server message on the GUI if it cannot connect, regardless of the cause. The VPN server specifies the secure gateway. If Always-on is enabled and a captive portal is not present, the client continues to attempt to connect to the VPN and updates the status message accordingly.

If the Always-on VPN is enabled, the connect failure policy is closed, captive portal remediation is disabled, and AnyConnect detects the presence of a captive portal, then the AnyConnect GUI displays this message once per connection and once per reconnect:

If AnyConnect detects the presence of a captive portal and the AnyConnect configuration differs from that previously described, the AnyConnect GUI displays this message once per connection and once per reconnect:

Caution: Captive portal detection is enabled by default and is nonconfigurable. AnyConnect does not modify any browser configuration settings during captive portal detection.

Captive Portal Hotspot Remediation

Captive portal remediation is the process where you satisfy the requirements of a captive portal hotspot in order to obtain network access.

AnyConnect does not remediate the captive portal; it relies on the end user to perform the remediation.

In order to perform the captive portal remediation, the end user meets the requirements of the hotspot provider. These requirements might include payment of a fee to access the network, a signature on an acceptable use policy, both, or some other requirement that is defined by the provider.

Captive portal remediation must be explicitly allowed in an AnyConnect VPN Client profile if AnyConnect Always-on is enabled and the Connect failure policy is set to Closed. If Always-on is enabled and the Connect Failure policy is set to Open, you do not need to explicitly allow captive portal remediation in an AnyConnect VPN Client profile because the user is not restricted from network access.

False Captive Portal Detection

AnyConnect can falsely assume it is in a captive portal in these situations.

• If AnyConnect attempts to contact an ASA with a certificate that contains an incorrect server name (CN), then the AnyConnect client will think it is in a captive portal environment.
  In order to prevent this issue, make sure that the ASA certificate is properly configured. The CN value in the certificate must match the name of the ASA server in the VPN client profile.
  
• If there is another device on the network before the ASA that responds to the client's attempt to contact an ASA by blocking HTTPS access to the ASA, then the AnyConnect client will think it is in a captive portal environment. This situation can occur when a user is on an internal network and connects through a firewall in order to connect to the ASA.
  If you must restrict access to the ASA from inside the corporation, configure your firewall such that HTTP and HTTPS traffic to the ASA's address does not return an HTTP status. HTTP/HTTPS access to the ASA should either be allowed or completely blocked (also known as black-holed) in order to ensure that HTTP/HTTPS requests sent to the ASA will not return an unexpected response.

Cisco Anyconnect Service

1. AnyConnect tries an HTTPS probe to the Fully Qualified Domain Name (FQDN) defined in the XML profile.
   
2. If there is a certificate error (not trusted/wrong FQDN), then AnyConnect tries an HTTP probe to the FQDN defined in the XML profile. If there is any other response than an HTTP 302, then it considers itself to be behind a captive portal.

Captive Portal Incorrectly Detected with IKEV2

When you attempt an Internet Key Exchange Version 2 (IKEv2) connection to an ASA with SSL authentication disabled that runs the Adaptive Security Device Manager (ASDM) portal on port 443, the HTTPS probe performed for captive portal detection results in a redirect to the ASDM portal (/admin/public/index.html). Since this is not expected by the client, it looks like a captive portal redirect, and the connection attempt is prevented since it seems that captive portal remediation is required.

Workarounds

If you encounter this issue, here are some workarounds:

• Remove HTTP commands on that interface so that the ASA will not listen to HTTP connections on the interface.
  
• Remove the SSL trustpoint on the interface.
  
• Enable IKEV2 client-services.
  
• Enable WebVPN on the interface.

This issue is resolved by Cisco bug ID CSCud17825 in Version 3.1(3103).

Caution: The same problem exists for Cisco IOS^® routers. If ip http server is enabled on Cisco IOS, which is required if the same box is used as the PKI Server, AnyConnect falsely detects captive portal. The workaround is to use ip http access-class in order to stop responses to AnyConnect HTTP requests, instead of requesting authentication.
