For advanced users, Virtual Service function allows the product to provide limited visibility to local
machines with specific services for outside users. An ISP (Internet Service Providers) provided IP
address can be set to the product and then specific services can be rerouted to specific computers
on the local network. For instance, a dedicated web server can be connected to the Internet via
the product and then incoming requests for HTML that are received by the product can be rerouted
to the dedicated local web server, even though the server now has a different IP address. In this
example, the product is on the Internet and vulnerable to attacks, but the server is protected.
Virtual Server can also be used to re-task services to multiple servers. For instance, the product
can be set to allow separated FTP, Web, and Multiplayer game servers to share the same Internet-
visible IP address while still protecting the servers and LAN users from hackers.
