Choosing an Application
A list of popular applications has been included to choose from. Click
on "Select a Service" then select your application from the drop-down
list. The settings will be transferred to the first row available. Click
"Add" to save the setting for that application.
Manually Entering Settings into the Virtual Server
To manually enter settings, click on "Custom Server" and enter a
name for the server. Enter the Server IP address in the space provided
for the internal machine and the port(s) required to pass. Then select
the protocol type (TCP or UDP), and then click "Add".
Opening ports in your firewall can pose a security risk. You can enable
and disable settings very quickly. It is recommended that you disable
the settings when you are not using a specific application.
Client IP Filters
The Router can be configured to restrict access to the Internet, email, or
other network services at specific days and times.
