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. 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
