By default, all the ports will be open (I am most certainly not an expert, so please correct me on anything I state in the post!).
If you are using ubuntu, then there is a helpful command line tool called "ufw" (the uncomplicated firewall) that can be used to configure iptables.
To use it, type sudo ufw enable
If I recall correctly, by default all incoming connections are blocked and all outgoing connections are allowed.
You can open a port by typing sudo ufw allow {portnumber}/tcp, where you replace {portnumber} with the port number that you want to open.
More information about ufw can be found here: https://help.ubuntu.com/community/UFW
