GateKeeper Proxy - Pro is a proxy server firewall application which allows your entire computer network to share a single Internet connection. GateKeeper Proxy - Pro eliminates the need to get a separate dial-up account, with a phone line and modem, for each user who wants access to the Internet. The program supports the following proxies: HTTP, FTP, Telnet, RealAudio, POP3, SOCKS4, SOCKS5, SSL, NetMeeting, Mapped Link (TCP), and Mapped Port (UDP). It also includes a Web caching algorithm designed to reduce network traffic, and features a DHCP server for dynamic network management, a public API enabling customers to write their own proxies, and customisable HTML pages allowing administrators to configure GateKeeper from their preferred browser. GateKeeper Proxy - Pro's user/policy management lets you restrict individual or group access to Internet services according to customizable settings. In addition, the program includes a powerful Web cache to boost the performance of browsing activity on pages previously visited by other network users and thus dramatically reducing online costs.
