In order to avoid any hackers attack, I want to block IP from Russian federation.
In RV345/firewall/Access rules, I can create rules to deny single IP, or range IP or subnet.
In range IP I cannot choose for example from 2.60.0.0 to 2.63.255.255.
Anyway there are a lot of IP addresses, and I cannot enter manually each rule.
So, I am asking if there is any method to load a file in an accepted format?How?
Thank you
