ACLs rules not working as expected
I am facing an issue with my ACLs configuration across the board, and I need some assistance to resolve it. I have set up several rules under IP extended rules and applied an IP binding configuration. Focusing on a subset of my network consists of three VLANs:
- VLAN 1: IP range 10.75.10.0/24
- VLAN 2: IP range 192.168.5.0/24
- VLAN 9: IP range 172.18.10.0/24
To allow specific services to work, I have configured certain IP/TCP ports.
To test the functionality of the ACL rules, I performed a simple ping test, and here are the results:
- Communication between VLAN 1 and VLAN 9: OPEN
- Communication between VLAN 1 and VLAN 5: BLOCKED
- Communication between VLAN 9 and VLAN 5: OPEN
What I expect ;
- Communication between VLAN 1 and VLAN 9: OPEN
- Communication between VLAN 1 and VLAN 5: BLOCKED
- Communication between VLAN 9 and VLAN 5: BLOCKED
I would appreciate any insights or suggestions on why the ACL is not functioning as expected. Thank you in advance for your help!

Goal is to stop communication between VLANs.
