4.4 Dynamic
DNS
Dynamic DNS (Domain Name System) 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 or other services).
This is for people with a dynamic IP address from their ISP or DHCP server that would still like to have a
domain name. You can also access your FTP server or Web site on your own computer using a DNS-like
address (for example, myhost.dhs.org, where myhost is a name of your choice), which 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.
To use this service, you must register with the Dynamic DNS service provider. The Dynamic DNS service
provider will give you a password or key.
4.4.1 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.
4.5 Configuring Dynamic DNS
To change your ZyWALL’s DDNS, click
SYSTEM

DDNS
tab. The screen appears as shown.
