Server
Select From ISP if your ISP dynamically assigns DNS server information (and the
HomeSafe's WAN IP address). The field below displays the (read-only) DNS server
IP address that the ISP assigns.
Select User-Defined if you have the IP address of a DNS server. Enter the DNS
server's IP address in the field below. If you chose User-Defined, but leave the IP
address set to 0.0.0.0, User-Defined changes to None after you click Apply. If you
set a second choice to User-Defined, and enter the same IP address, the second
User-Defined changes to None after you click Apply.
Select None if you do not want to configure DNS servers. If you do not configure a
system DNS server, you must use IP addresses when configuring VPN, DDNS and
the time server.
Apply Click Apply to save your changes back to the HomeSafe.
Reset Click Reset to begin configuring this screen afresh.
4.3 Dynamic DNS
Dynamic DNS allows you to update your current dynamic IP address with one or many dynamic
DNS services so that anyone can contact you (in NetMeeting, CU-SeeMe, etc.). You can also
access your FTP server or Web site on your own computer using a domain name (for instance
myhost.dhs.org, where myhost is a name of your choice) that will never change instead of using
an IP address that changes each time you reconnect. Your friends or relatives will always be able
to call you even if they don't know your IP address.
First of all, you need to have registered a dynamic DNS account with www.dyndns.org. This is
for people with a dynamic IP from their ISP or DHCP server that would still like to have a
domain name. The Dynamic DNS service provider will give you a password or key.
4.3.1 DynDNS Wildcard
Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be aliased to the
same IP address as yourhost.dyndns.org. This feature is useful if you want to be able to use, for
example, www.yourhost.dyndns.org and still reach your hostname.

If you have a private WAN IP address, then you cannot use
Dynamic DNS.

shown.
