Microsoft VPN
Outgoing
Ports Type - Select the protocol (TCP or UDP) used when you send data to the
remote system or service.
From - Enter the beginning of the range of port numbers used by the
application server, for data you send to it. If the application uses a
single port number, enter it in both the "From" and "To" fields.
To - Enter the end of the range of port numbers used by the application
server, for data you send to it. If the application uses a single port
number, enter it in both the "From" and "To" fields.

Using a Special Application

• Configure the Special Applications screen as required.
• On your PC, use the application 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, there may need to be a "Time-out" before another PC can use the same
Special Application. The "Time-out" period may be up to 3 minutes.
If an application still cannot function correctly,
try using the "DMZ" feature.

DMZ

This feature, if enabled, allows one (1) device /
PC on your LAN to be exposed to all users on the
Internet.
This allows unrestricted 2-way communication between the "DMZ PC" and other Internet
users or Servers.
• This allows almost any application to be used on the "DMZ PC".
• The "DMZ PC" will receive all "Unknown" connections and data.
• If the DMZ feature is enabled, you must select the PC to be used as the "DMZ PC".
The "DMZ PC" is effectively outside the Firewall,
making it more vulnerable to attacks. For this reason,
you should only enable the DMZ feature when required.
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:
1. You must register for the service at www.dyndns.org using the dyndns.org domain.
2. After registration, follow the Service Provider's procedure to request a Domain Name, and
have it allocated to you.
