If the port mapping is unsuccessful and you have a UPnP compatible router, make sure:


If you have an Apple Airport, make sure NAT-PMP is enabled. To do this:

  1. Open Airport Admin Utility
  2. Select your base station and click "Configure".
  3. In the "AirPort" tab, click "Base Station Options...".
  4. In the "Ethernet Port Security" tab, check the "Enable NAT Port Mapping Protocol" checkbox.
  5. Click "OK".
  6. Click "Update".

    NB: NAT-PMP requires MacOS X 10.4 Tiger, as well as up to date Airport software and firmware.

If you are still having problems, open the message log (in the Window menu) and post the debug output on the support forums.
