This page assumes you have the basic knowledge required to edit resources in Helix using Rezilla. See this page for an overview on editing resources with Rezilla.

PORT resource #1 (referred to as ‘PORT/1’ controls the TCP/IP port Helix Client/Server uses for TCP/IP communications. The default port for Helix is 10860, but this number can be changed to avoid conflict with other TCP/IP applications, to enable access to multiple Helix Servers via NAT, or to provide ‘security through obscurity.’ Your network administrator may also require that you use specific ports.

Note: A Helix Client can not access a Helix Server using an alternate port unless you either a) edit the Helix Client PORT resource #1 to the same port or b) connect to the Server using the full IP Address:Port syntax (e.g. 192.168.0.100:10865)

The PORT/1 resource is a single field, containing a 2 byte decimal value in the range of 0-65535. Simply change this value to the desired port, click Save, and close the editor. (Be sure to save the modified application when quitting Rezilla.)

Editing resources is much easier if you have the corresponding templates installed. See the sections on templates on the Rezilla overview page.

Helix applications are created in ‘package’ format, with the resources being found in a file within the package. If you are familiar with package manipulation, you can open the application package, navigate to the resource, and drag/drop it onto Rezilla. For those less technical, here are instructions for changing Helix Server 6.1.x. (The same steps apply to Helix Client.):

1. Launch Rezilla.
2. Select Open from the file menu.

3. Navigate to the Helix Server you want to edit. When you select the application, Rezilla will show you the contents of the application package. The path to follow to the resources is:

   Contents -> Resources -> Helix Server.rsrc

   (For Helix Client, the name of the resource is Helix Client.rsrc.)

   (In Helix Server macOS 6.0, the path is Contents -> MacOSClassic -> Helix Server macOS)

4. Click Open.
5. In the window that opens, scroll down until you see the PORT resource line.

6. Click the disclosure triangle next to the resource. An entry with the numbers 1 & 2 appears.

7. Double-click directly on one of the two numbers. The editor window opens.

8. Make your changes, click Save, and close the window.
9. Choose Save from the file menu.
10. Quit Rezilla.
