Snort - Blocking Attack but no blocking hosts

[bartounet16]

Hello.
I have upgrade my firewall with new hardware powerfully

So i have installed and activated Snort.

It works well and detect attacks.

But how block attack without blocking host ??

I feel like we have no choice but to block the entire host

I used to work with stormshield, and the ips block only attacks them and not the ip address
