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


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.

Does not require the VPN:

  • eLeave, eRequest, eProfile and many other OSU services.
  • Box, Carmen/Canvas, Zoom, Code42 and other cloud services.
  • University Email System, Office 365 apps.
  • Guacamole for Windows Remote Desktop to Windows machines and ASC Standard Linux machines running xrdp.
  • 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 stongly encouraged to use Jump, but if the VPN is required we suggest using openconnect (see related articles) instead of the Cisco client.


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

1. OCIO provides the Cisco AnyConnect VPN Client:

  • Go to:
  • Login with your lastname.# and Duo.
  • Click on "Order Services"
  • Click on "Software Services"
  • Click "NEXT"
  • Select "Cisco AnyConnect"; click "NEXT"
  • Select the operating system you are using.
  • Continue until checkout.
  • You wil receive an email with a download link; download the software.
  • Install the software from the zip file.

Note: If you are on an ASC-owned computer, you can use Software Center (Windows) or Self Service (Mac) to download the program without needing administrator rights.

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 - 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,, 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.
