Is there a particular reason for why you want to run a firewall? I'm
asking because in the default install, no remotely exploitable services
run besides DHCP, and thus a firewall doesn't really buy you anything.

I don't know whether running a firewall inside the vm makes any sense at
all, maybe someone else can comment on that.

The new Ubuntu default firewall is ufw:
<http://www.ubuntu.com/getubuntu/releasenotes/804overview#head-a1ab2f26d9a7785e3570aec6974de7ad07e55002>

It can only be configured from the command line. However, Linux
firewalls in general are just frontends to the kernel's iptables, and so
I can't see a reason why you shouldn't be able to run firestarter
instead of ufw, if you really need a firewall because you opened certain
ports.
