General Configuration

The General Configuration section sets up the basic proxy services and also has a few options to add some mandated policies such as virus scanning and user authentication.

To configure the proxy all the options on this screen must be completed. A description of each item can be found by clicking on the name of the item.

Proxy Administrator

The Proxy Administrator field requires an e-mail address. This e-mail address will be displayed when end-users receive errors from the proxy.

Address To Listen On

This is the address you want the proxy server to answer requests on. Generally you want this to be the internal address so users on the inside can access the proxy server to the outside. On a non-gateway, this is the IP of the only interface.

Port To Listen On

The proxy server by default will use port 8080. Port 3128 is also a common proxy port. If you are uncertain what to enter leave the default of 8080.

Transparent Proxy?

The Transparent Proxy option forces user traffic to be redirected through the proxy regardless of their web browser configuration. Proxy Authentication can not be enabled if Transparent Proxy is enabled.

Mandate Proxy?

Enabling the Mandate Proxy option will force the users to use the proxy by denying them access to the web via port 80. However, this requires the user configured their web browser for the proxy and in turn allows Proxy Authentication to be enabled.

Traffic Shaping?

Traffic Shaping allows the proxy server to control the amount of bandwidth the proxy server will allow each user to use. You can select the amount of bandwidth usage from the pull-down menu. Each rate shows the actual throughput in parenthesis.

For example 56kbit is about the speed of a 56k modem while, 512kbit is about equivalent to a standard DSL connection and 1.544Mbit is the equivalent of a T1 line.

Each user will receive a percentage of the overall available bandwidth based on the number of concurrent users versus the total bandwidth selected.

Virus Scanning Host

Enabling Virus Scanning will allow the EnGarde Proxy Server to scan specific files with defined file extensions for viruses. For example, all '.EXE' and .'ZIP' files. Enabling Virus Scanning here will add the Virus Scanner Configuration menu to the Proxy Management section allowing the Virus Scanner to be configured in detail. There is a separate section dedicated to the Virus Scanner Configuration in Section on page .

• [NOTE:]Transparent Proxy, Mandate Proxy and Traffic Shaping are only valid if the proxy server is located between the internal and external networks.
