Firewall rules are not applied immediately

Hi everyone!
I installed OPNsense 23.1.7 and everything works fine.
However, even if the rule is disabled in the firewall rule, the network goes out from the local to the outside.
No new internet, but already connected sessions continue to work.

How can I immediately block an already connected sessions?
