As an alternative to downloading the Cisco VPN client for Mac OS X, you can also use the built in IPSec version found on your machine. This might be more convenient for those who wish to avoid installing additional software.

You will need an Account in order to access the Mac VPN.

 

1. Head over to your System Preferences and to the Network Settings. 

System Preferences > Network 

 

2. Add a New interface. 

 

3. Input the following settings: 
Interface: VPN 
VPN Type: Cisco IPSec 
Service Name: This can be anything, I left the default. 

 

4. Edit the new interface details as follows: 
Server Address: cisco.vpntraffic.com
Account Name: Your vpn account
Password: Your vpn password

 

5. Click on the Authentication Settings... button as shown above. 
Both the Shared Secret and Group Name should be entered as: ipsec 

Hit OK and now you should be able to press Connect. This will prompt you for your password and after a successful authentication, you will now be connected to the  VPN.

You can also check the Show VPN Status in Menu Bar box for easier access later.
