Linux pretty much IS a firewall. If you did a default install, then you don't need to do anything special. You don't need to run UFW or Firestarter, or any one of a zoo of firewall scripts.
Why? because by default, Ubuntu doesn't run any naughty services.
So, just relax and enjoy your Ubuntu system.
respectfully, that only pertains to the incoming side of a firewall and the "open" ports argument often used.
Outbound rules are just as important, regardless of listening services naughty or not, application code can be exploited to bind to arbitrary ports and hackers/crackers can create reverse connections.
Tight outbound policies can help to eliminate this.
Security is a process not a product.
Security is a process not a state.
