UD General Proxy Service

Introduction

Some computers and devices must be kept on a non-routable network, meaning are not able to connect to outside networks, such as the Internet. It is important that these devices be able to get patches and updates. A proxy can allow devices on a non-routable network to connect to an outside network so that they can get patches and updates. The UD general HTTP/HTTPS proxy instance was set up to allow devices with private IP addresses on campus (generally referred to on campus as net 10 or 10.x.x.x IP addresses), to access and download patches and other updates from off-campus. 

A proxy is an intermediary server that acts as a gateway between a user's device and the Internet. When you use a proxy, your Internet traffic is routed through the proxy server before reaching its destination, thus adding an additional layer of security. A good example of proxy server use is a university lab with computers for sensitive research that must be kept secure. 

Important: This proxy service is NOT intended for use on servers, especially those that contain level 2 or 3 data. Instances for server use are forthcoming.

Please also note the following:

• If your computer is on the same subnet as a server, then it will not be allowed access to the general proxy service.

• This proxy cannot be used with the UD VPN.

• This proxy should not be used to connect compromised systems to the network.

• This proxy should not be used with computers that are out-of-date and therefore security risks, such as Windows XP.

• The proxy service is not to be used with compromised systems.

• Logs will be routinely audited to verify that no servers are connecting to the proxy.

How to configure device proxy settings

The service can be used by configuring device HTTP and HTTPS proxy settings as follows:

proxy.escs.udel.edu:5000
