Easy Port Forwarding: Applying Pre-Defined Rules
Available pre-defined rules are categorised according to the application type. Click
the Radio Button adjacent to the appropriate Category, and then select the required
application name. Click on the Add button to move the application into the Applied
Rules box. In the example shown on the previous page, 'Delta Force' has been se-
lected from the list of Available Rules and is about to be copied to Applied Rules. In
the example, this will configure your Modem ports to use with 'Delta Force' .
