Faster Than a Speeding VPN--Super Remote Access With Neoteris IVE

In a conventional VPN setup, a user authenticates from the Internet to a VPN server on the corporate LAN, and all traffic between the user and the LAN is encrypted. However, to access a VPN the user must install client software. The IVE eliminates this need by deploying SSL tunneling and acting as an application proxy, which means you must be on a network that passes HTTPS (Port 443) traffic. Connections are made from the user to the IVE, and then the IVE opens a connection and passes data to the internal server. Some activities, such as file sharing and SSH, are "Webified"--transformed into a Web-browser-based interface. Other TCP-based programs and services are proxied and tunneled through a Java applet using SSL.

I plugged the IVE into the Network Computing network at our Syracuse University Real-World Labs®. Using an Apple Macintosh and a Microsoft Windows NT box as clients, I connected through an external broadband link and set up a Microsoft Exchange 2000 and Internet Information Server (IIS) running Windows 2000 on the private LAN. The IVE includes two Ethernet ports--you can use just one port or use the second port as a DMZ. I installed the IVE in one-arm mode.
