Snort and fail2ban, iptables

[Guest]

[samuel]

Hello. I started fail2ban, configured filter.d for snort. Filter.d
[Definition]

failregex = .*snort.*Priority: 1.*} <HOST>.*
#        .*snort.*Priority: 2.*} <HOST>.*

I have configured jail.local
 
Although fail2ban bans ip, iptables doesn't ban those apis, I still see them active. How could I add this rule in iptables to block ips banned by fail2ban? Thank you !
