CU VPN Configuration

The information contained on this page is not a custom VPN setup for CCAR use only. This is the same VPN offered by OIT but the directions found here are more concise for users to follow.

If you are not part of CCAR, please consult with OIT and/or your Computer Support Representative to configure the VPN correctly. CCAR support cannot help anyone outside of Aerospace Engineering Sciences.

Let's all celebrate the decommission of the Juniper VPN!!

Here is the link that provides detailed directions on how to install the Cisco AnyConnect software for all platforms. Please refer to this page when following the directions below for your operating system.
