Dynamic DNS (Domain Name Server)
This free service is very useful when combined with the Virtual Server feature. It allows
Internet users to connect to your Virtual Servers using a URL, rather than an IP Ad-
dress.
This also solves the problem of having a dynamic IP address. With a dynamic IP
address, your IP address may change whenever you connect, which makes it difficult
to connect to you.
The Service works as follows:
1. You must register for the service at http://www.dyndns.org (Registration is free).
Your password will be E-mailed to you.
2. After registration, use the "Create New Host" option (at www.dyndns.org) to re-
quest your desired Domain name.
3. Enter your data from www.dyndns.org in VRT-401’s DDNS screen.
4. VRT-401 will then automatically ensure that your current IP Address is recorded at
http://www.dyndns.org
5. From the Internet, users will be able to connect to your Virtual Servers (or DMZ PC)
using your Domain name, as shown on this screen.
