IP access list in RV345

[Alexman11]

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

These are small business routers, i do not see that feature like any NGFW has geo-based ACL.

You need to do it manually
