Dynamic DNS
Dynamic DNS 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 each time you connect to your ISP, making it difficult to connect to you.
You must register for the Dynamic DNS service. The Multi-WAN VPN Link Balancer supports 3 types
of service providers:
•
Standard client, available at http://www.dyndns.org
(Other sites may offer the same service, but can not be guaranteed to work)
•
TZO at http://www.tzo.com
•
3322 is available in China at http://www.3322.org
To use the Dynamic DNS feature
1.
Register for the service from your preferred service provider.
2.
Follow the service provider's procedure to have a Domain Name (Host name) allocated to you.
3.
Configure the Dynamic DNS screen, as described below.
4.
The Multi-WAN VPN Link Balancer will then automatically update your IP Address recorded by the
Dynamic DNS service provider.
5.
From the Internet, users will now be able to connect to your Virtual Servers (or DMZ PC) using
your Domain name.
