#Country ban with UFW#
Grab your different country ip addresses and save as Linux IPTables

##Add country## Run the following command
while read line; do sudo ufw deny from $line; done < all.txt
Where the filename is the country.
##Remove country## To remove or revert these rules, keep that list of IPs! Then run a command like so to remove the rules:
while read line; do sudo ufw delete deny from $line; done < all.txt
##Suggestion## What I did was exported each individual country as their own country.txt file. But then realized that I wanted to run this thing one time, so I ran the following command:
cat *.txt >> all.txt
Then you can run your rule against all of the files.
Definitely get the CIDR format—and not the Linux IPTables one—if you are going to use those commands, otherwise you'll only receive syntax errors.
Thank you both, by the way!
