Special Application List - This list shows the details for all currently defined Special Applications. You can modify its configuration data by mouse clicking the appropriate row.
Using a Special Application on your PC
When the Special Applications screen is configured correctly, you can use the application on your PC normally. Remember that only one (1) PC can use each Special application at any time.
Also, when 1 PC is finished using a particular Special Application, a “Time Out’’ period may be required before another PC can use the same Special Application.
If an application still cannot function correctly, try using the "DMZ" feature instead.
Advanced configuration – 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 on your WAN port. With a dynamic IP your IP address may change whenever you connect to your ISP, which makes it difficult for visitors to connect to your web site.
You must register for the Dynamic DNS service. The VPN800/8 F Firewall 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
Register for the service from your preferred service provider.
Follow the service provider's procedure to have a Domain Name (Host name) allocated to you.
Configure the Dynamic DNS screen, as described below.
The VPN800/8 F Firewall will then automatically update your IP Address recorded by the Dynamic DNS service provider.
From the Internet, users will now be able to connect to your Virtual Servers (or DMZ PC) using your Domain name.
