Fast application of Rules, and NAT (PFsense)

t feels like im struggling to understand things and when im making changes in pfsense. As if rules dont apply right away. Is this because of the established states staying alive before the rule actually works. Is there a way to make it so the changes i make happen immediately

Thank you !!

You can create the rules then clear the states.System Monitoring — Firewall States — Reset State Table / Source Tracking Table | pfSense Documentation
