Chapter 4 Smt Menu 1 - General Setup; System Name; Dynamic Dns - ZyXEL Communications ZYWALL 10W User Manual

Menu 1 - General Setup contains administrative and system-related information.
4.1

System Name

System Name is for identification purposes. ZyXEL recommends you enter your computer's "Computer
name".
•
In Windows 95/98 click Start -> Settings -> Control Panel and then double-click Network. Click
the Identification tab, note the entry for the Computer name field and enter it in the ZyWALL
System Name field.
•
In Windows 2000 click Start->Settings->Control Panel and then double-click System. Click the
Network Identification tab and then the Properties button. Note the entry for the Computer name
field and enter it in the ZyWALL System Name field.
•
In Windows XP, click start -> My Computer -> View system information and then click the
Computer Name tab. Note the entry in the Full computer name field and enter it as the ZyWALL
System Name.
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.
4.2

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).
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) 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 DNS name.
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. The ZyWALL supports www.dyndns.org. You can apply to this
service provider for Dynamic DNS service.
