Googled and found nothing recent. I did find docs on ufw and I ran:

thomas@Westeros:~/git/heavyweight-software$ sudo ufw status verbose
[sudo] password for thomas:
Status: inactive

So I'm thinking it isn't running ufw anymore. I can ping my computer, but I can't connect to it on my development web server port 4200. Can't find any docs on ubuntu site either.

Finally found the answer here:

The answer appears to be that ufw is disabled by default and there is a default policy in place that doesn't use that. So I ran:

sudo ufw enable

And then ran

sudo ufw allow 4200

now sudo ufw status verbose returns me the information I wanted to see.

Additionally, taught me to run ng serve --host 0.0.0.0 to serve my angular app outside of localhost.

sudo ufw allow 4200

This will open port 4200
