Connect Device to Mac localhost Server?

Question

How do I allow any device, e.g., iPhone, to connect over a WLAN to my Mac's localhost server?

On my Mac, I'm running a "Hello World" HTTP Node.js server that serves a page, which Safari opens successfully, at http://localhost:1337. And, running ipconfig getifaddr en1 in Terminal outputs 192.168.1.9.

But, Safari, on both iPhone & Mac, displays "Safari can't connect to the server" when it tries to open http://192.168.1.9:1337.

I don't think this should involve port forwarding because I only want the HTTP server to be available privately, not publicly.

Answer 1

Have your server listen on 0.0.0.0 instead of localhost.
