Question about UFW

[mahesh]

Hi All,
On this helpful wiki link (https://wiki.ubuntu.com/BasicSecurity/Firewall), there is a section about setting up transmission rules:

Transmission rules

sudo ufw allow out 51413/tcp
sudo ufw allow out 51413/udp
sudo ufw allow out 6969/tcp


What is the purpose of those rules and do I need them if I don't have a server set up, but am only using a laptop with a basic internet connection?
