Perproxy

Perproxy is a simple http proxy server that allows you to share your Internet connection with other computers. If you have a local network and only one, or just a few, computers have direct Internet access, this service makes it possible to share the web with the computers that don't have direct access. Just run the proxy server on the computer(s) that have the direct connection, and indicate the name or IP address of the proxy in their web browser (Internet Explorer, Mozilla, Netscape, Opera, etc) of the other computers. The program allows you to limit access to a couple determined IP addresses, doesn't require installation, is completely free, and is available in Spanish. Could you ask for anything more?
