LevelOne WBR-3470 - Manual (Page 5)

The 11g Wireless ADSL2+ VoIP Router provides two levels of security support. First, it
masks LAN IP addresses making them invisible to outside users on the Internet, so it is
much more difficult for a hacker to target a machine on your network. Second, it can block
and redirect certain ports to limit the services that outside users can access. To ensure that
games and other Internet applications run properly, you can open specific ports for outside
users to access internal services on your network.
The Integrated DHCP (Dynamic Host Control Protocol) client and server services allow
multiple users to get IP addresses automatically when the router boots up. Simply set local
machines as a DHCP client to accept a dynamically assigned IP address from the DHCP
server and reboot. Each time a local machine is powered up; the router recognizes it and
assigns an IP address to instantly connect it to the
LAN.
For advanced users, Virtual Service (port forwarding) functions allow the product to provide
limited visibility to local machines with specific services for outside users. You can set an
ISP (Internet Service Provider) provided IP address on the 11g Wireless ADSL2+ VoIP
Router and then you can reroute specific services to individual computers on your local
network. For instance, a dedicated web server can be connected to the Internet via the
router and then incoming requests for web pages that are received by the router can be
rerouted to your dedicated local web server, even though the server now has a different IP
address.
Virtual Server can also be used to re-task services to multiple servers. For instance, you can
set the router 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.
