DNS Setup
The DNS is used to resolve the DNS name to IPs. You can type the DNS name or obtain it automatically.
The Dynamic DNS feature allows you to host a server (Web, FTP, Game Server, etc.) using a domain name that you have purchased (for example:
www.whateveryournameis.com) with your dynamically assigned IP address. Most broadband Internet Service Providers assign dynamic (changing)
IP addresses. Using a DDNS service provider, your friends can just enter your host name to connect to your game server without having to know
your IP address.
To access the
DNS
setting window, click on the
DNS
button under the
ADVANCED
tab.
DNS AND DEFAULT GATEWAY
If you are using the router for DHCP service on the LAN and are
using DNS servers on the ISP’s network, check the
Obtain DNS
server address automatically
box.
If you have DNS IP addresses provided by your ISP, enter these
IP addresses in the available entry fields for the
Preferred
DNS Server
and the
Alternate DNS Server
.

Firewall & DMZ
The router already provides a simple firewall by virtue of the way NAT works. By default NAT does not respond to unsolicited incoming requests on
any port, thereby making your WAN invisible to Internet cyber attackers.
DMZ means Demilitarised Zone. DMZ allows computers behind the router firewall to be accessible to Internet traffic. Typically, your DMZ would
contain Web servers, FTP servers, and others.
FIREWALL SETTINGS
Enable the Firewall by clicking
Enable Firewall
.
Enable the SPI on clicking
Enable SPI
.
Enable the ALG on clicking
Enable ALG
.
