Port forwarding

Remote forwarding

Let a server reach a service running on your Mac or in your network.

Example

You’re building a web app on your Mac at localhost:3000 and want a service on web-server to send webhooks to it.

1. In Port Forwarding, click New Forwarding and choose Remote.
2. Connect via host: web-server.
3. Requested remote listener: port 8080. This is the port that opens on the server.
4. Destination: 127.0.0.1, port 3000.
5. Click Save & Connect.

Everything that reaches port 8080 on the server now arrives at your app on port 3000.

Good to know

• The destination is seen from your Mac. It can be your Mac itself or another machine on your network.
• Most servers accept connections to the forwarded port only from the server itself. To open it to other machines, the server must allow it (GatewayPorts in its SSH settings).

ssh -R 8080:127.0.0.1:3000 user@web-server
