Virtual Private Network FAQ


The University of Chicago virtual private network (cVPN) provides faculty, students, and staff with secure access to University network resources as if you are on campus, no matter where you are in the world. The cVPN can be used to remotely access resources that are not available to you when you're off-campus. You should also use the cVPN when you are working on an unknown network such as a hotel or coffee shop wireless network.

How do I access cVPN?

You can access cVPN by logging in to cvpn.uchicago.edu with your CNetID and password. You will need to verify your identity using two-factor authentication (2FA) in order to access the cVPN. Upon logging in, your operating system will be detected, such as Windows or Mac, and then it will prompt you to download the appropriate AnyConnect VPN app for your computer's operating system.

Who can use cVPN?

Current faculty, students, and staff of the University are eligible to use cVPN. A current student is defined as a student taking classes in the current quarter.

Can I use cVPN if my computer is running Linux?

The cVPN client is supported on the following Linux distributions: Linux Red Hat 8 and 7 & Ubuntu 20.04, 18.04, and 16.04 (all x64). IT Services does not support the installation and configuration of the cVPN client on Linux. The installer packages (32-bit and 64-bit) are available for advanced users who support themselves or have divisional IT support for Linux.

Can I use cVPN with older versions of Windows or MacOS?

IT Services does not support cVPN use with Windows versions before 11, nor Apple MacOS versions lower than 14.8.7.

Can I use cVPN with Windows 11 ARM64 based PC?

Yes, a special ARM based installer is available. Please submit this request that gets routed directly to the networking team.

What is the IP address range of cVPN?

The cVPN's current IP address range is 205.208.120.0/22. When you connect to the cVPN, you'll obtain an IP address within the 10.190.128.0/20 range. When you access campus or online resources, cVPN will perform the same function that allows multiple computers on a home network to utilize a single Internet connection, Port Address Translation (PAT). Once the traffic leaves the cVPN, it will appear as if you are using the 205.208.120.0/22 IP range. This is done as an effort to efficiently utilize the IP space on campus, as well as ensure campus resources are still accessible from cVPN.

How do I connect to cVPN with a mobile device?

You can download Cisco AnyConnect for your Android or iOS, and most other mobile platforms. Support is limited for mobile devices.

Does cVPN work while traveling abroad?

For the most part, cVPN functions as intended while traveling abroad. However, some countries have laws restricting the cryptographic software that VPNs utilize. Countries like China have measures in place that block VPN usage. Please refer to the Travel Tips and Technology knowledge base article for up-to-date information related to technology use while traveling abroad.

Could I run multiple VPN applications simultaneously? 

No.  The way VPNs work is to force network traffic through a VPN tunnel.  Having multiple VPN applications open simultaneously would cause a conflict on where the computer should send traffic.  This conflict causes traffic to be dropped. 

Why can't I print or access local resources while on cVPN?

cVPN is considered a "full tunnel" VPN.  This means that the VPN logically makes your computer appear as if its on campus.  This configuration is intentional.  Besides accessing campus resources remotely, cVPN is meant to allow people to safely browse the Internet while on unfamiliar/public networks.  In order for the later to be possible, all network traffic must go through the VPN.  Because of this, local resources will not be available.

Are there installation guides available?

Yes. See the list below:
