Hardware Installation & Initial Setup
The Domain Name entry is what is propagated to the DHCP clients on the LAN. If you leave this field
blank, the domain name obtained by DHCP from the ISP is used. While you must enter the host name
(System Name) on each individual machine, the domain name can be assigned from the ZyWALL via
DHCP.
2.7.1 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 DNS-like address (e.g. 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.
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 DNS name.
To use this service, you must register with the Dynamic DNS client. The Dynamic DNS Client service
provider will give you a password or key. The ZyWALL at the time of writing supports
www.ddns.org
and
www.dyndns.org
clients. You can apply to either of these clients for Dynamic DNS service.
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.
