Firewall - Technical Information & Server Registration

CU-Boulder is "closed" network meaning that, by default, traffic is not allowed into the campus network with the following exceptions:

  • IP Security Protocol (IP protocol ID 50, IP protocol ID 51, UDP port 500)

*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.

Firewall & Server Registration

Overview

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.

Cost

The firewall is a common-good service provided to the campus. Exceptions can be made at no-cost with the appropriate business or academic justification.

Wired Internet - 1Gb (GigE) Connections

Overview

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 DNS

Overview

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.

Features

Client systems should be on subnets in private IP address space.
 Client systems should be participating in the campus Active Directory.

IP Address and Hostname Management

Overview

OIT assists customers with name and address management by providing Static IP addresses and Dynamic DNS. Learn more about getting a Static IP address below.

About Static IP Address Assignments

Static IP addresses are needed for devices such as printers or servers that need the same IP address all the time.  DHCP (Dynamic Host Configuration Protocol) is the campus standard and should be used for all devices that do not need a static IP address. A Static IP address must be assigned by OIT and it must be manually configured in the device, it is not configured automatically. Static IP addresses are not assigned for UCB Wireless.

Features

Features

Dedicated IP address for your computer, server, printer, or device that does not change.
