The ISI Tunnel

Abstract

The ISI Tunnel allows sites that are hidden behind 'firewalls' , also known as 'gatekeepers' or 'mail-bridges' , to have IP-based internet access without being open to attacks over the internet. The Tunnel is a special router that provides smooth seamless internet access from a closed environment, the 'inside' , to the 'outside' while restricting the access from the outside to the inside. The advantage of the Tunnel, in comparison with traditional firewalls, is that it supports any IP-based communication; not just terminal access, file transfer, and electronic mail.
