Ubuntu has all the ports close by default. It has iptables as a firewall.
To open ports you can use a GUI utility like Firestarter or you can use the command line utily ufw that is installed already. These are just front-end managers.

Here's is an example to some configuration using ufw (uncomplicated firewall)

NAME
fwb_compile_all - Wrapper script that compiles policies for multiple firewall objects SYNOPSIS
fwb_compile_all -ffile.xml [-dwdir] [-av] [obj[ obj ...]] DESCRIPTION
fwb_compile_all is a wrapper script that compiles policies for several firewall objects in one batch job. This script takes a list of fire- wall object names on the command line (or '-a' command line option, see below) and calls policy compiler for each one. The script correctly determines which policy compiler is needed depending on the firewall platform of each object. OPTIONS
-a The script processes all firewall objects in the "/Firewalls" subtree. -d wdir Specify working directory. Compiler creates file with iptables script in this directory. If this parameter is missing, then ipta- bles script will be placed in the current working directory. -f FILE Specify the name of the data file to be processed. -v Script passes this option to the compiler, this makes it print diagnostic messages indicating its progress.
