How to run node.js as non-root user?

Question

I\'m running a node.js server, that will serve requests on port 80 amongst others. Clearly this requires the application running as root (on Linux).

(I haven't got enough reputation to add a comment the the one of Matt Browne, so I write this as an answer. Feel free to edit.)

There is a simpler method to load iptables rules automatically after a reboot than the one described in the link of Matt Browne: One can install iptables-persistent from the repositories using apt-get:

apt-get install iptables-persistent

Rules still need to be saved manually like this:

IPv4:

iptables-save > /etc/iptables/rules.v4

IPv6:

iptables-save > /etc/iptables/rules.v6
