Overview
A VPN (Virtual Private Network) provides a secure encrypted tunnel from
your computer to CU's network whether you are on campus or off. If you
are using the client from off campus, it appears that your computer
traffic is originating from the CU network thus allowing access to resources that require on-campus connections such as library resources.
Off-campus connectivity
On-campus connectivity
- Sometimes when on-campus using UCB Wireless or even a wired connection in an office, it's necessary to use the CU-Boulder VPN to be granted access to a particular system.
- In most instances, you'll informed that you need to connect to the VPN to have access to system. But if you're not and you're having trouble getting access, give it a try and that might be the solution.
Who needs VPN?
- Customers who have a non-CU ISP, who need access to CU resources,
like the library. VPN is not needed for secure services such
as a CU e-mail account.
- Customers wanting secure access via the campus wireless network.
Who does not need VPN?
- Customers that don't need to connect to CU-Boulder resources.
- Customers accessing ITS e-mail with SSH or Authenticated SMTP.
- Customers accessing ITS servers with SSH.
- Customers using SSH to access servers (e-mail or otherwise) that
are registered with the IT Security office.
- Customers browsing the internet or making file transfers from off
campus sites.
IdentiKey is required
An IdentiKey is required to make a connection to the VPN. In addition to an IdentiKey, you must have the proper entitlements to get access, such as being a CU-Boulder student, faculty, or staff member.

Description |
| Network Connect |
Network Connect is an application that you can install and use to have an on-campus network connection when you are away from campus or on UCB Wireless. Use this application to access on-campus resources like the libraries and still have access to your home networked devices. |
| VPN Web Interface |
A simple web-based VPN connection that allows access to on-campus and off-campus resources, such as the library, through a web browser. It also connects to many services besides web browsing (remote desktop, SSH, file sharing). Allows for a simultaneous connection to the CU-Boulder network and your home network. |
| Cisco VPN |
Cisco VPN is the application that ITS has provided to the campus for years. It provides a VPN connection that routes all traffic through the campus network. It does not allow for split tunneling, and home networked devices cannot be accessed while using this type of connection. It does not work on 64-bit operating systems. |
What is it:
- Network Connect is an application that you can install and use to have a secure on-campus network connection when you are away from campus or on UCB Wireless. Use this application to access on-campus resources like the libraries and still have access to your home networked devices.
Why use it:
- Client—Much like the Cisco version of VPN that ITS has provided over the years, Network Connect is a program that you install, and then run when you want your whole computer to be connected to the CU-Boulder network.
- Full access—Use Network Connect when you need to access UCB Libraries resources, use an SSH program to access an on-campus server, connect to an on-campus file share, or use an e-mail program (such as Outlook) that needs to have an on-campus connection from off-campus.
- Printing—You can still connect to your home network as well for printing.
- Public IP—All of your network traffic will be routed through the CU-Boulder campus network, even when you are off campus.
