A Secure and Transparent Firewall Web Proxy

Roger Crandell, James Clifford, and Alexander Kent, Los Alamos National Laboratory


The LANL transparent web proxy lets authorized external users originating from the Internet to securely access internal intranet web content and applications normally blocked by a firewall. Unauthenticated access is still, of course, denied. The proxy is transparent in that no changes to browsers, user interaction, or intranet web servers are necessary. The proxy, a few thousand lines of C running on Linux, has been operating within Los Alamos National Laboratory's firewall since 1999.
