I am trying to create a firewall rule to block the traffic from certain referrals. There are about 30 domain types, sending bot traffic to my website. These domain types are .club, .xyz, .online, etc.
And I am trying to block the traffic that comes from any of those domain types, instead of specific domains.
So, I was wondering how can we use wildcard expression in the firewall rules to block them on the domain type level?
