Moonlight Internet Streaming Helper v2.2

This program can automatically configure your home network to allow streaming from your gaming PC over the Internet using Moonlight. If problems occur, the included testing tool can provide automatic diagnosis and suggestions of how to address various network issues.

Instructions

For the easiest possible setup process, we highly recommend that you first pair Moonlight with your gaming PC while connected to your home network before trying to use Moonlight over the Internet.

If your gaming PC is already paired with Moonlight:

1. Install mish-2.2.msi on your gaming PC.
2. Run "Moonlight Internet Streaming Tester" via the Start Menu to confirm it's working properly.

If your gaming PC is not already paired with Moonlight:

1. Install mish-2.2.msi on your gaming PC.
2. Run "Moonlight Internet Streaming Tester" via the Start Menu.
3. Type the IP address that is displayed on the tester's success dialog into the Add PC dialog of Moonlight.
   • You must ensure your Moonlight client is not connected to the same network as your gaming PC during this step or the connection may not be successful.

Having trouble?

• Ensure UPnP is enabled in your router settings and delete any older Moonlight port forwarding entries.

• Try streaming from a different network. Some corporate or public WiFi networks block streaming applications like Moonlight. If that happens, you can try the ZeroTier setup steps.

• Ask for help on our Discord server. Be sure to have the log from the Moonlight Internet Streaming Tester handy.

Limitations

• Port forwarding is limited to one GameStream PC per public IP address. This means you should only install this program on one PC on your network to avoid conflicts. To stream from multiple PCs on your home network while away from home, you can try the ZeroTier setup steps.

Changes in v2.2

• Added help links to error dialogs
• Fixed issues preventing the tool from working properly if google.com was blocked
• Fixed a bug handling responses from certain routers
