Connecting to the Virtual Servers
Once configured, anyone on the Internet can connect to your Virtual Servers. They must use the
Internet IP Address (the IP Address allocated to you by your ISP).
e.g.
http://203.70.212.52
ftp://203.70.212.52
It is more convenient if you are using a Fixed IP Address from your ISP, rather than Dynamic.
However, you can use the
Dynamic DNS
feature, described in the following section, to allow
users to connect to your Virtual Servers using a URL, rather than an IP Address.
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 Address.
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:
•
You must register for the service at http://www.dyndns.org (Registration is free).
•
Your password will be E-mailed to you.
•
After registration, enter and save your DDNS username and password on this screen, and
also your preferred Domain name.
•
If your preferred Domain name is unavailable, a message will be displayed. Enter another
name, keep trying until you find some variation which is available.
•
The Broadband Router will then automatically ensure that your current IP Address is
recorded at http://www.dyndns.org
•
From the Internet, users will now be able to connect to your Virtual Servers (or DMZ PC)
using your Domain name, as shown on this screen.
