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 fin-
ished 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.

Multi-DMZ

This feature, if enabled, allows one (1) or more computers on your LAN to
be exposed to all users on the Internet.
• If you only have 1 WAN IP addresses, only DMZ 1 can be used. This
uses the primary IP address (which may be dynamic), so you do not
have to enter it.
• If you have multiple WAN IP addresses, you can specify a DMZ PC for
each IP address. You must enter the other WAN IP addresses which are
allocated to you.
The DMZ feature 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 sent to
the corresponding IP address from the Internet.
If an application still cannot function
correctly, try using the "DMZ" feature.
