I have an esxi6 host on public ip. All other VMs are behind pfsense firewall, so no issues.
I can't put esxi behind that because I don't want to get locked out.
So far I have disabled ssh access to esxi host.
Now for other security I just want to block ping messages to public ip of esxi host that no one knows if that ip is alive so that no one so any brute force attacks etc.
Is there any way I can block ping messages?
