Blocking Europe from attempted rdt logins

[rpolomano]

Please advise where in opnsense has the ability to block ip addresses.  I have 4 servers that allow rdt connections with users.  There have been at least 10 - 20 attempted logins all from European countries which are blocked at individual servers.
How can I block these ip addresses manually at the opnsense firewall.
I would like to block all of Europe if possible,
Thanks in advance

Your place to start would be Aliases.

Specifically, look for the section on how to configure GeoIP alisases.
