General Notes
The VPN is currently a full tunnel, meaning all traffic will be routed through it. For linux machines, this means NFS will be disrupted while you are connected. For the Mac, this means that IM clients and mail will disconnect and reconnect (hopefully) upon the change in IP.
To access the supercomputers Bluehive and Bluegene of Center for Integrated Research Computing (CIRC) from outside the University of Rochester, VPN access is required. Following is the link to install CISCO VPN :
