# This script configures ufw to forward traffic from port 8080 to port 80

# Confirm the installation of ufw
sudo apt-get install ufw -y

# Enable the UFW firewall
sudo ufw enable

# We need to allow incoming traffic on port 8080/TCP
sudo ufw allow 8080/tcp

# Now, we need to modify the UFW configuration file to set up port forwarding

# Finally, we need to reload the UFW firewall for our changes to take effect
sudo ufw reload
