Hey Jason,

You could setup default firewall rules that allow outgoing connections, but not incoming ones. Assuming you need ports 22 and 80 open, it's as simple as:

ufw default deny incoming

ufw default allow outgoing

ufw allow ssh

ufw allow http

ufw enable

Check out this article for more info on using ufw to setup firewall rules:

This is exactly what I needed. Thank you!
