Cisco AnyConnect VPN provides a secure encrypted tunnel from your computer or mobile device to the CU-Boulder network, allowing you access to on-campus resources (e.g. library resources, file servers) both on and off campus.
The VPN web interface, available at https://cuvpn.colorado.edu, and the Network Connect VPN application will be retired on Thursday, February 5.
eduroam (educational roaming) is a secure wireless network service available to all CU-Boulder faculty, staff, and students, as well as members of hundreds of participating institutions world-wide.
You have successfully connected to the CU-Boulder network.
The CU-Boulder campus network registration service is going through a phased upgrade. This upgraded registration service will periodically require reregistration. If you have questions about the new network registration service or the reregistration process, please contact the IT Service Center. Contact information is at the bottom of this page.
CU-Boulder is "closed" network meaning that, by default, traffic is not allowed into the campus network with the following exceptions:
*NOTE: None of these changes impact outgoing Internet traffic (for example, web browsing, connecting to external mail servers, etc) only traffic from the Internet attempting to connect to campus systems is affected.
The campus border firewall is part of a comprehensive and broad-based OIT security program to protect campus users from malicious online attacks. A firewall is a device or set of devices designed to permit or deny network transmissions based upon a set of rules and is frequently used to protect networks from unauthorized access while permitting legitimate communications to pass.
Campus units that need to provide access to services from the Internet can request an exception; however, departments are strongly encouraged to use the VPN service as an alternative to seeking a border firewall exception.
To most desktop users the firewall does not have an impact on daily operations. An exception would be for those that need to access some on-campus services, such as Windows Remote Desktop, from an off-campus location. In this case, use of a VPN client is necessary to connect to your computer or other campus resource. Learn more about using the campus's VPN client.

By 2013 it is expected that the campus-wide standard will evolve from 100 megabit connections to 1 gigabit (GigE). (GigE is the equivalent of 1 billion bits per second, or 1,000 Mbps.) In the meantime, GigE is provided to those whose work would be impeded without GigE. This typically impacts those conducting research computing or those who do large data transfers.
Dynamic Domain Name Service (dDNS) is available to systems participating in the Campus Active Directory (AD). DDNS allows system administrators to configure their client systems to announce their own chosen name along with the IP address that was assigned to that client by the Dynamic Host Configuration Protocol (DHCP) server. This can facilitate easier management of groups of client systems without needing to use static IP addresses.
