How Do I Connect to the ASC VPN Using Cisco and Duo?

Overview

The ASC VPN provides secure remote access to ASC resources.

Note: Please, do not use the VPN if your service does not require it.

There are many services that do not require the VPN. The VPN adds overhead (slowness) to connections and there are finite slots available on the VPN.

Requires the VPN:

  • Connecting to shared and private Windows drives.
  • Re-validating your Windows license if the machine has not connected to the OSU network for 180 days.

Does not require the VPN:

  • Workday, Compass, and many other OSU services.
  • OneDrive, Carmen/Canvas, Zoom, Code42 and other cloud services.
  • University Email System, Office 365 apps.
  • Remote Desktop to Windows or Linux running XRDP:
    • ASC's RDP Gateway is preferred for on campus and off campus connections.
    • Guacamole for Windows Remote Desktop to Windows machines and ASC Standard Linux machines running xrdp.
      • Guacamole has the advantage that it doesn't require a client, just a web browser.
    • As of February 2, 2021, RDP will cease to function over the VPN.
  • SSH to Linux machines using Jump. (This includes Unity.)
  • SFTP to Linux hosts, this can be tunnelled through Jump and is faster.

Linux users are strongly encouraged to use Jump, but if the VPN is required we suggest using openconnect (see related articles) instead of the Cisco client.

Procedure

How do I connect to the ASC VPN using Cisco and Duo?

1. Install the client:

  • If you are on an OSU owned computer:
    • Windows: find the Cisco client in Software Center 
    • Macintosh: find the Cisco client in Self Service
    • These will install without needing administrator rights.
  • Otherwise, please use the clients attached to this KB.
    • Windows:
      • Download anyconnect-win-4.9.05042-core-vpn-predeploy-k9.msi, ASC-AnyConnect-client-profile.xml, and Install-CiscoAnyConnect49.cmd
      • Double click the .cmd file. If Windows Smart Screen complains, it's ok to allow.
      • The install may take up to 25 minutes.
    • Macintosh:
      • Download and run the .pkg file.
      • Check only the VPN checkbox for the components to install.

2. Once the program has been installed, open it. On a Mac, you can open it in Applications, but on Windows 10, I just searched for it in the Start Menu.

3. In the dropdown field, type vpn.asc.ohio-state.edu - this address will be saved next time you want to connect.

4. You will be prompted for your group, username, password, and second password.
For group: Select “ASC-VPN” for access to all OSU on-campus resources. Select “ASC-VPN-TunnelAll” to be able to access off-campus resources, as well as on-campus resources as though you were on campus. The “ASC-VPN-TunnelAll” is useful for directly accessing journals from the publisher’s site, for instance.
For username: Use your name.#.
For password: Use your OSU password (used for email, Carmen, my.osu.edu, etc.).
For second password: Your second password will be from Duo. If you use Duo on a smart device, you can either:

  • type “push” and then click OK, and confirm the push on your mobile device OR
  • go into Duo on your mobile app and request a passcode by pressing the key button

5. Click Accept on the Window that pops up.


6. Cisco will give you the green checkmark when you’re connected.
