I repeat again. The IP is not the problem. It is the SYS-Firewall plugin
I have also found another bug, after trying to add other countries for testing. For example I add CHINA and do an iptables -S the following is given away.
-A INPUT -m set --match-set CN src -j DROP
But the moment I restart the server (VPS) and do an iptables -S again it disappears. If I go to the AAPANEL panel and go to the SYS-Firewal plugin and go to the country blocking tab again, the country CHINA is still added.
The plugin is definitely not working properly.
I'm going to disable it.
