2.8General Setup

Menu 1 - General Setup contains administrative and system-related information. The fields for General Setup are as shown next. System Name is for identification purposes. However, because some ISPs check this name you should enter your PC’s “Computer Name” (Start -> Settings -> Control Panel -> Network. Click the Identification tab, note the entry for the Computer name” field). It is the domain name that will be propagated to the DHCP clients on the LAN. If you leave this 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 Prestige via DHCP.

2.8.1 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.) or 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 your 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 Prestige 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.
