iptables installed by default but its not configured or enabled.
$ sudo iptables -L
[sudo] password for jonas:
Chain INPUT (policy ACCEPT)
target     prot opt source               destination

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

There is also a frontend (UFW) in ubuntu for iptables and it's
installed by default but not used.
$ sudo ufw status
Status: inactive

Ufw is what i think Ubuntu is going to use as they has started to ship
rules for ufw in the packages. On a default install of Jaunty i have
this rules.
$ sudo ufw app list
Available applications:
