Cut and paste the following lines into the new file and save it.

# Cut/Copy from here -
while read -r line; do
ufw allow from "$line" to any port 80;
ufw allow from "$line" to any port 443;
done < ips-v4

while read -r line; do
ufw allow from "$line" to any port 80;
ufw allow from "$line" to any port 443;
done < ips-v6
# Cut/Copy above this line.

chmod +x filename.s
sudo ./filename.s

WARNING: If this is the first time you've used UFW on your server, don't forget to open the port for SSH.
