10.3 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.
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.
A If you have a private WAN IP address, then you cannot use Dynamic DNS.

LABEL DESCRIPTION
System Setup
System Name Enter your computer's "Computer Name". This is for identification purposes, but
some ISPs also check this field. This name can be up to 30 alphanumeric
characters long. Spaces are not allowed, but dashes “-” and underscores "_" are
accepted.
Domain Name Enter the domain name entry that is propagated to DHCP clients on the LAN. If
you leave this blank, the domain name obtained from the ISP is used. Use up to
38 alphanumeric characters. Spaces are not allowed, but dashes “-” and periods
"." are accepted.
Administrator
Inactivity Timer
Enter the number of minutes a management session can be left idle before the
session times out. After it times out, you have to log in again. A value of "0" means
a management session never times out, no matter how long it has been left idle.
This is not recommended. Long idle timeouts may have security risks. The default
is five minutes.

New Password Enter the new password for the WiMAX Modem. You can use up to 30 characters.
As you type the password, the screen displays an asterisk (*) for each character
you type.
