Your question looks really broad, however just to mention that "Ubuntu has pre installed firewall and a Set of Rules what so called "IPTABLES".

You can do

sudo ufw status #this gives you the status if firewall is active or inactive

or

sudo ufw enable #enables the firewall

or

sudo ufw -h #displays all possible options

To enable the firewall just type sudo ufw enable ssh #this will enable firewall for ssh.

You can add some rules using iptables Command

sudo iptables -L -n #will list available rules for IPTABLES such as (INPUT, OUTPUT,NAT,etc.)
