Solutions > Education Control Web AccessThe Web Proxy (Optional) This service appears to the local network to be a web server, and page requests made to the proxy are forwarded to other servers on the Internet. Most web browsers support the use of web proxies, making it possible to operate your entire network through a single Internet connection. When a user wishes to browse a page not available on the local network, their browser requests the page from Mailtraq. Mailtraq can handle any number of simultaneous connections. This works in harmony with your mail and news services, so while some are browsing, other users can collect new e-mail. Configuration Options Edit Outgoing Firewall Mailtraq provides an editable list of URLs and IP address specifications in an Outgoing Proxy Firewall. This firewall can be configured to deny Web Proxy access to any connecting client or to any range of external URLs for each configured client. An empty firewall permits all connecting clients (which have passed through the HTTP Service firewall) to access all external URLs. Click on Edit Outgoing Firewall to display and edit this firewall. Select the following for further information on this option:-
