Answer by Michael Bernheiden for How to access NodeJS server on LAN?

First, you need to add C:\Program Files (x86)\node to the list of trusted applications in your firewall.

Then, in your node app, you can write:

listen(3333, '172.24.14.26', function() {

or:

listen(3333, '0.0.0.0', function() {

or:

listen(3333, function() {

or:

listen(80, '172.24.14.26', function() {

or:

listen(80, '0.0.0.0', function() {

or:

listen(80, function() {

Each one of these 6 combinations work in my case: node.js on Windows Server 2016, protected by a company proxy.
