$ sudo ufw statusStatus: activeTo Action From-- ------ ----Nginx Full ALLOW Anywhere 22/tcp ALLOW Anywhere Nginx Full (v6) ALLOW Anywhere (v6) 22/tcp (v6) ALLOW Anywhere (v6) How can I allow SSH (22/tcp) requests only from a certain region, country or continent?
This question is not related to allowing only requests from localhost, for example, because the IP of locahost is already known. I want something like to have all the IP ranges of a certain country in a text file and embed them into ufw allow rule.
