Adding a Service
If these options do not meet the requirements for a user's network, it is easy to add another. To illustrate, we will add an entry for an IRC (Internet Relay Chat) Server. This TCP-based program uses default port of 6667.
Right click on Network Neighborhood and click on Properties
Right click the connection using the ICF and select Properties
Click on the Advanced tab and choose Settings
Click on the Services tab
Click Add
Enter the following information
Description of service: IRC Server
Name or IP address of the computer hosting this service on your network: IP address where IRC software is installed
External port number for this service: 6667
Internal port number for this service: 6667
Click TCP
Click OK, OK, and then OK again to exit to the Network Connection window

Editing and Deleting a Service
In the case that a Services settings need adjusted or deleted, the user can follow the instructions given under Adding a Service. However, instead of choosing the Add button on the Services window, a user should choose Delete or Edit. Once the Service has been changed, it will be saved when the user clicks OK.
