Port forwarding

Local forwarding

Open a service that only your server can reach, such as a database, as if it were running on your Mac.

Example

Your PostgreSQL database runs on db-server and only accepts connections from the server itself. You want to open it in a database app on your Mac.

1. In Port Forwarding, click New Forwarding and choose Local.
2. Connect via host: db-server.
3. Listen on this Mac: 127.0.0.1, port 5433.
4. Destination: 127.0.0.1, port 5432.
5. Click Save & Connect.

Now point your database app to localhost:5433.

Good to know

• The destination is seen from the server. 127.0.0.1 means the server itself; you can also enter another machine in the server’s network.
• Pick a listening port that isn’t already used on your Mac.

ssh -L 5433:127.0.0.1:5432 user@db-server
