Mac OS X Built-In Cisco VPN Client
From MCS IT Wiki
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 ANL Domain Account in order to access the VPN.
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 ANL VPN.
You can also check the Show VPN Status in Menu Bar box for easier access later.
