firewall. This may be necessary if the firewall is causing problems with an application such as
a game or video conferencing application. Use this feature on a temporary basis. The
computer in the DMZ is NOT protected from hacker attacks.

Using Dynamic DNS
The Dynamic DNS service lets you alias a dynamic IP address to a static host name in any of
the many domains DynDNS.org offers, allowing your network computers to be more easily
accessed from various locations on the Internet. DynDNS.org provides this service, for up to
five host names, free to the Internet community.
The Dynamic DNSSM service is ideal for a home Web site, file server, or to make it easy to
access your home PC and stored files while you’re at work. Using the service can ensure that
your host name always points to your IP address, no matter how often your ISP changes it.
When your IP address changes, your friends and associates can always locate you by visiting
yourname.dyndns.org instead.
To register free for your Dynamic DNS host name,

WAN ping blocking
Computer hackers use what is known as
pinging
to find potential victims on the Internet. By
pinging a specific IP address and receiving a response from the IP address, a hacker can
determine that something of interest might be there. Your router can be set up so it will not
respond to an ICMP ping from the outside. This heightens the level of security of your router.
To turn off the ping response
•
Open the
Firewall > WAN Ping Blocking
page and select
Block ICMP Ping
, then click
Apply Changes
. Your router will not respond to an ICMP ping.
Utilities tab
This screen lets you manage different parameters of your router and perform certain
