How to use Duo with Caltech VPN

Duo multi-factor authentication is required for access to the Caltech VPN. To sign into the Caltech VPN using Duo:

  1. Open Cisco Secure Client, enter "vpn.caltech.edu" and select "Connect"
  2. Two windows will open at this point. Note that one may be hidden from view behind the other window.
  3. First, use the smaller window with a dropdown selection box for VPN group. Make sure the correct group is selected:
    1. 1-Tunnel-Caltech-Traffic-Only: only traffic destined for Caltech systems uses the VPN. Use this default option in most cases.
    2. 2-Tunnel-All-Traffic: all network traffic uses the VPN.
  4. After selecting the VPN group, find the larger web browser window. You should see the familiar Microsoft-based login page with the Beckman Institute background image. Complete the sign in using username@caltech.edu and your access.caltech password.
  5. After successfully entering your username@caltech.edu and your access.caltech password, you may be prompted by Duo. Use one of your configured second-factor authentication methods to complete the process.
