ACL Rule Question - Permit X to Y also permit Y to X

Hello

I'm working on ACL for all my vlan's and I have a question :

 

 

 

Why does 192.168.15.0/25 network can ping 192.168.1.0/24 ?

I did some tests and it comes from the rule allowing IP traffic from 192.168.1.0/24 to 192.168.15.0/25

Traffic from 15.0 to 1.0 isn't allowed

Is that normal that a rule allowing IP works in both ways ?

 

Thanks for your answers ;)

  • Hi

    Could someone confirm how ACL IP Rules work, coz it really seems weird that a rule can apply in both direction.

    If it's normal then how to I restrict traffic in ony one direction ?
