So I have installed the Apostrophe-CMS per http://aclouda.com/blog/services/how-to-install-apostrophe-content-management-system-on-ubuntu/ on my Oracle Cloud Infrastructure Ubuntu compute instance and I configured my security list to allow port 3000.
node app.js results in "Listening at http://localhost:3000"
When attempting to reach the server over port 3000 either in telnet or browser, it times out.
Checking sudo netstat -tunlp | grep :3000 results in:
tcp6 0 0 :::3000 :::* LISTEN 1397/node
I am not seeing a tcp 127.0.0.1:3000 line item which I would expect to see. Is there something I need to do to set the app to listen on port 3000 for tcp?
This was related to Oracle using iptables by default. Solution identified in this stackoverflow comment.
