Do I need to restart my instance for firewall rules to apply

Question

I have a Windows 2016 server instance running a node.js website on Google Cloud Engine (please don't ask why). The node.js app does this:

var server = http.createServer(app);
server.listen(3000);

which, according to the node documentation, listens on every interface. And indeed, if I connect to the 10.132.x.x address from there, I do see the website. However, it seems that the port is blocked by the firewall for outside connections.

So I created a new firewall rule which allows tcp:3000 for instances tagged properly. But that doesn't seem to work.

Do I need to restart my instance? Or do anything else?

Ah, silly me. There is also a firewall on the windows instance itself.
