How to display client ip on localhost node server?

Question

Node.js

var getClientAddress = function (req) {
    return (req.headers['x-forwarded-for'] || '').split(',')[0] 
        || req.connection.remoteAddress;
};

Displayed ip 127.0.0.1.
How to be?
app.enabled('trust proxy')
Did not help.

Try the "X-Forwarded-For" header case, but most likely the proxy simply does not set it, you need to configure nginx or haproxy or whatever is used there.
