  2. Download the AnyConnect file for MacOS.
  3. Open the DMG and double click on AnyConnect.pkg.
  4. Accept the license agreement and complete the installation.
  5. Only the VPN needs to be installed - The other add-ons can be unchecked (currently not used by OSU).
  6. Note: If all of the installation options are grayed out, try uninstalling previous versions of Cisco AnyConnect first.
  7. Follow steps to allow the Cisco System Extension if prompted.
  8. When complete, you should see the message "The installation was successful."

Connect to the VPN

  1. Open the Cisco AnyConnect Secure Mobility Client
  2. Enter vpn.oregonstate.edu and click connect.

    Caution: If you see "sds.oregonstate.edu" in the server name, please change it to "vpn.oregonstate.edu".

  3. A Cisco AnyConnect Login screen will appear with a connection type window behind it.
    1. Full tunnel vs. Split Tunnel selection: Hidden behind the login screen will be another window labeled "Cisco AnyConnect | vpn.oregonstate.edu" with a drop-down menu to select your connection type. 
    2. Full tunnel is the initial default for most users. If you switch from full tunnel to split tunnel, the split tunnel option will remain selected in future. For details about which to use, see: VPN - Full Tunnel vs. Split Tunnel
    3. Enter your OSU username and password in the login window and click "Login". You will be prompted to do Duo two-step login.
