My server appeared to under DOS attack

My server location is not supported for DOS protection. Therefore I checked the Vultr firewall instead. However, it appears that it does not support blocking.

For now, I blocked the IP from ufw. I would like to know if there is a way to use Vultr firewall to block specific IP addresses.

    Hello Kelvin,

    The Vultr firewall will block all IPs that are not explicitly listed in the allow rules you defined. You can read more about the Vultr Firewall feature here:

    If you require a block only rule for a single ip, you can achieve this through os-level firewall tooling (ufw/iptables/etc)
