With a default Ubuntu installation there are no open ports, unless you
have installed extra servers. For a simple installation like your's the
firewall (which is nothing more than a frontend for iptables rules)
should block incoming traffic from the internet to open ports on the
machine. But as there are no open ports, there is no need to add a
firewall or use any iptables rules.
