How is VPN different from the proxy server?
The proxy server provides access to most licensed resources. However, some programs do not work with the proxy server. These require VPN for off-campus use: ARTstor (Macintosh only), Luna Insight, MDL Crossfire Beilstein and Gmelin, SciFinder Scholar (client version only), the java client in UC Image Service, and the Connect function in EndNote. Another difference is that the proxy server requires a one-time change in your web browser settings, then prompts you when you need to log in. VPN is a “client” software program that you download and install on your computer. You must run the VPN client each time you want to use licensed resources.
