nftables example for Debian 10 in 2020

This video has a very basic example of setting up and troubleshooting nftables so that it allows the ports for Minecraft and ssh, and drops everything else. I do not claim to be an expert on this, but I made this video out of frustration after spending a full day of reading the wikis on nftables and still being confused. It is meant to just give an example of a nftables configuration that works for a Minecraft server, by modifying /etc/nftables.conf directly and then restarting the service.
