Ticket — Expose Local Dev Server to Remote Tester

Description:

A QA tester sits on test-srv and needs to test a web app that a developer is running locally on dev-box at port 3000. The developer’s machine is behind a NAT/router — the tester cannot reach dev-box directly.

The developer needs to expose their local port 3000 so that the tester can access it from test-srv on port 9090.

1. Create the correct SSH tunnel so that test-srv:9090 forwards to your local dev-box:3000
2. Run it in the background
3. Confirm the tunnel is listening on test-srv
