This wouldn't be efficient in my case. I'm testing a frontend that's served on localhost:80 and connects to a local backend also on localhost:80 that makes DB calls to some remote database on 3306. I'd have to modify the backend code to connect through the proxy port every time I wanted to test it. As it is the backend code on my computer is a mirror of the production environment. Normally if I tunnel I have it set up to forward everything through the tunnel except localhost.
