Configure manual port mapping on your broadband router

To configure a manual port mapping on your broadband router, follow the instructions below:

Open your broadband router configuration screen. Normally this is done via your web browser using the address of your broadband router. For example: http://192.168.1.254/. Please consult the manual for your broadband router for IP address and login instructions. (Note: Apple’s Airport uses an application called “Airport Utility” instead of a web browser to configure it.)

Find the port mapping screen. (It is sometimes called the port forwarding screen.) The screen will be different for each broadband router model, but generally you will be asked to enter the following information:

  • Application name: Enter ‘Slink’. (You can call it whatever you like, but ‘Slink’ is probably a good name!)
  • External start port and end port: Enter the external port configured in the Slink Agent System Preferences pane for both the start and end port. For example: 443. (Some broadband routers only allow you to enter a single external port instead of a start and end port range. If that is the case, enter the external port from step 2 above.)
  • Internal host IP address: Enter your Mac’s static IP address from. For example: 192.168.1.200.
  • Internal host start port and end port: Enter 22 for both the start end end port. Port 22 is the Remote Login (SSH) port.
  • Protocol: Choose TCP. (‘Protocol’ may not be an option on some broadband routers.)

The portforward.com web site provides detailed information on how to configure port mappings for a large number of broadband router models.

Save your settings. Please note that some broadband routers must be restarted for changes to take effect.
