Proxy servers provided on the firewall can allow, for example, internal users to use Netscape Navigator(TM) to access the World Wide Web, to use ftp to transfer files between a host on the internal network and one on the Internet, or to telnet to an external host for an interactive session.
The two most common proxy server solutions are server-side proxies and the SOCKS proxy server. The proxy servers available with the optional Gauntlet(TM) for IRIX firewall implement server-side-only applications, in which one proxy server exists for each supported application. The SOCKS approach utilizes a socksd process on the server, and then requires any application that communicates with it to be "SOCKSified" that is; compiled with the SOCKS library. The Netscape Navigator(TM), for example, comes already "SOCKSified."
