Network Security
With this router, you can easily connect to your ADSL 
broadband line for Internet access in your office or at home. 
This device automatically creates an IP number and assigns 
for each user, simplifying everyone's logon operation. 
A standard-based ADSL modem in built into this router, 
making connection to the Internet a breeze. The router also 
incorporates four 10/100Mbps Ethernet switch ports, 
providing ready connection for workstations and servers, 
while saving you the cost and trouble of installing a separate 
Ethernet switch.
The router provides NAT protection for your office and 
home users from any Internet intruders and hackers, plus 
VPN pass-through for extra security. It also blocks and 
redirects certain ports to limit the services that outside users 
can access your network. Virtual server mapping is used to re-
task services to multiple servers. This router can be set to 
allow separate FTP, Web, and Multiplayer game severs to 
share the same Internet-visible IP address while still 
protecting your servers and workstations from hackers. 
The router supports constricted DMZ to redirect unknown 
packets to a dedicated server/PC behind the router, enabling a 
client (such as a Web server) to fully expose it to the Internet 
and ensure complete Internet application compatibility. This 
allows you to set up web sites and e-commerce business from 
your office while maintaining protection for the rest of your 
office LAN.
