Configuring Cisco Anyconnect VPN 'Cisco Anyconnect Configuration File'

====================================================================

This article provides step-by-step instructions on how to configure a Cisco AnyConnect Virtual Private Network (VPN) connection using the Adaptive Security Device Manager (ASDM).

Prerequisites

----------

* A functioning Cisco ASA firewall with ASDM access.

* Basic knowledge of VPN technology and network security concepts.

Step 1: Accessing ASDM

----------------

1. Open your preferred web browser, such as Google Chrome or Mozilla Firefox.

2. Navigate to the IP address or hostname used to manage your ASA device via ASDM (usually http:///asdm).

3. Enter valid administrator credentials when prompted and click 'Log In'.

Step 2: Configuring AAA Server Groups

----------------------------------

1. After successful login, navigate through the left-hand menu under 'Configuration' > 'Remote Access VPN'.

2. Click on 'AAA/Local Users', then select 'Server Groups' from the drop-down list.

3. Click the '+' icon to create a new AAA server group.

Step 3: Adding RADIUS Server

------------------------

1. In the Add AAA Server dialog box, enter a name for your radius server under 'Group Name'.

2. Select 'radius' as the protocol type in the dropdown menu below it.

3. Enter the IP address or hostname of your Radius server and its respective port number(s) separated by commas if required.

Step 4: Creating VPN Client Profile

--------------------------------

1. Click on 'VPN > Cisco AnyConnect Clientless SSL/IPsec'.

2. Under AAA/AAA Server, select the previously created RADIUS server group.

3. Give a meaningful name to your profile under 'Profile Name'.

4. In the 'Group Tunnel' field, enter any descriptive text (optional).

5. Ensure that both 'IKEv2', and 'EAP-FAST' are selected in their respective fields.

Step 6: Delivering Configuration Changes

------------------------------------

1. Click on 'Apply' to save your changes.

2. Wait for a few seconds until the configuration is delivered to all ASA devices in the ASDM cluster (if applicable).

Troubleshooting Tips:

-----------------

* Ensure that you have entered correct IP addresses, usernames and passwords when configuring RADIUS server details.

* Double-check if IKEv2 and EAP-FAST are enabled on both client-side AnyConnect software as well as Cisco ASA firewall.

With these steps completed successfully, your users should now be able to establish a secure VPN connection using their configured Cisco Anyconnect Clientless SSL/IPsec profile.
