for a hacker to target a machine on your network. Secondly, it can block and redirect
certain ports to limit the services that outside users can access. For example, to ensure
that games and other Internet applications will run properly, user can open some specific
ports for outside users to access internal services in network.
Integrated DHCP (Dynamic Host Control Protocol) services, client and server, allow
multiple users to get their IP addresses automatically on boot up from the product. Simply
set local machines as a DHCP client to accept a dynamically assigned IP address from
DHCP server and reboot. Each time local machine is powered up; the router will
recognize it and assign an IP address to instantly connect it to the
LAN.
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.
