Configuring SSL VPN for Anyconnect

Posted on November 28, 2010

0



The AnyConnect client provides remote end users running Microsoft Vista, Windows XP or Windows 2000, Linux, or Macintosh OS X, with the benefits of a Cisco SSL VPN client, and supports applications and functions unavailable to a clientless, browser-based SSL VPN connection. In addition, the AnyConnect client supports IPv6 over an IPv4 network.

The AnyConnect client can be installed manually on the remote PC by the system administrator. It can also be loaded onto the security appliance and made ready for download to remote users. After downloading, it can automatically uninstall itself after the connection terminates, or it can remain on the remote PC for future SSL VPN connections.

In the following example I configure ssl vpn with rsa secureid and then with certificate. It is possible to configure both of them in the same time.

First you need to upload the image files for svc. I already did that and configured as well. I uploaded 2 kinf of images, one for linux and one for windows.

# sh webvpn svc
1. disk0:/anyconnect-linux-2.5.2001-k9.pkg 1 dyn-regex=/Linux i[1-9]86/
CISCO STC Linux

CISCO STC win2k+
2,5,2001

2 SSL VPN Client(s) installed

In the first example we use for authentication an RSA Secureid.

webvpn
port 444
enable outside
dtls port 444
svc image disk0:/anyconnect-linux-2.5.2001-k9.pkg 1
svc image disk0:/anyconnect-win-2.5.2001-k9.pkg 2
svc enable

tunnel-group AnyconnectTest type remote-access
tunnel-group AnyconnectTest general-attributes
authentication-server-group (outside) mysdigrp

dhcp-server 8.8.8.8
tunnel-group AnyconnectTest webvpn-attributes
authentication aaa
group-alias SSLVPNClient enable
!
aaa-server mysdigrp protocol sdi
aaa-server mysdigrp (inside) host 10.10.10.10 mykey

In the following example we use a certificate for the ssl vpn. Lets assume that the trustpoint and the client certificate is already configured.
For the certificate creation part the following document can help:

The successful login looks like the following, in the log.
