Cisco AnyConnect VPN 2.3 Installations

There are two phases of installation to consider, installing the AnyConnect VPN client files on the Adaptive Security Appliance (ASA) for automated download and install to systems, and the actual install on the remote PCs themselves. This document provides an overview of both phases.

The files needed for installation are located at http://www.cisco.com/pcgi-bin/tablebuild.pl/anyconnect.

Loading the AnyConnect VPN Software on the ASA

Use the copy command to copy the image file to the flash of your ASA. Then use the svc image command from webvpn configuration mode to identify the file as the client package file. You can install many different packages for different operating systems and use the svc image command to order them from most popular (lowest number) to least popular (highest number).

Enabling AnyConnect SSL VPN Connections on the ASA

Here is sample configuration that enables the AnyConnect VPN client connections on the ASA:

ASA1(config)# webvpn

ASA1(config-webvpn)# enable outside

ASA1(config-webvpn)# svc enable

ASA1(config)# ip local pool ACVPN 192.168.1.225-192.168.1.250

mask 255.255.255.0

ASA1(config)# tunnel-group REMOTEVPN general-attributes

ASA1(config-tunnel-general)# address-pool ACVPN

ASA1(config-tunnel-general)# default-group-policy SAMPLEDEFAULT

ASA1(config)# tunnel-group REMOTEVPN webvpn-attributes

ASA1(config-tunnel-webvpn)# group-alias DEFAULT_ALIAS enable

ASA1(config)# webvpn

ASA1(config-webvpn)# tunnel-group-list enable

ASA1(config)# group-policy SAMPLEDEFAULT attributes

ASA1(config-group-policy)# webvpn

ASA1(config-group-webvpn)# vpn-tunnel-protocol svc

Automating the Installation for Remote PCs

Be sure to follow these recommendations:

• If using a Certificate Authority (CA) for certificates on the ASA, configure the certificate as a trusted CA on client machines
• If using a self-signed certificate on the ASA, install it as a trusted root certificate on client machines
• Ensure the Common Name (CN) in the ASA certificates matches the name clients use to connect
• If you are using Cisco Security Agent (CSA), warnings will most likely display to end users during install
• For Microsoft Internet Explorer installations, install the ASA to the list of trusted sites; this may be automated using Active Directory
