Please support banning of entire countries via geoiplookup.
Many attacks originate from China and countries alike. My website has no intended audience whatsoever in such a country and I would like to ban all IP traffic from a certain country. Adding countries to /etc/hosts.deny will only block a small part of that traffic since most connections are based on IP address only, not on domain names.
Fail2ban can be extended to block failed attempts (or even any attempt) to login from a specified list of countries.
With the increase of attacks from countries that are totally outside of the range of the intended audience, this feature would increase security enormously.
