#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.
I have a repo with a ufw blocklist solution: (https://github.com/poddmo/ufw-blocklist)
There is also a solution there for multiple blocklists (eg per country, bogans, etc) that tests well for me and I just need to document its use.
In particular, check out the method I use to load list into the ipset. It spawns a subshell into the background so as not to hang the system while the list is loaded.
