Off campus? Use AnyConnect at http://vpn.bu.edu.

The easiest VPN client for off-campus use is AnyConnect. Because AnyConnect is web based, there is nothing you need to install or configure manually. To use AnyConnect, you simply login and wait for the connection to launch. A light client is downloaded when you connect, and disconnected when your computer shuts down. You can browse the web as you normally would, once the connection has been established.
