We have just been hacked.
The IP address appears to come from the Ukraine.
How can I block a range of IP addresses (ideally I want to block all IPs from outside the UK but I am guessing this is probably very complicated!)
A command I have found using google is:
/sbin/route add -host 192.168.0.123 reject
where the 192... address is the IP to block.
I want to block everything starting on this list:
18.104.22.168 to 22.214.171.124
