Vlan acl issue

    Posted 26 days ago

    I'm trying to create an acl and I can't get it working right. I am trying to block vlan 7 from vlan 18, but not Vlan 18 from vlan 7. I created the acl below and applied it to vlan 7 with IP access-group vlan7acl in. Problem is it is blocking vlan 7 from 18 and vlan 18 from vlan 7. I feel like it should work the way I want it to, but isn't. Thank you.

    10 deny ip

    Permit ip any any

    I assume you have tested connectivity to work without acl(?) Also assuming that vlan7 = and vlan18 = Which switch model we are talk about? (I assume L3 version >=6200)

    If you put such ACL to vlan7's outbound traffic, you cannot get answer back from vlan7 to vlan18. I think you need stateful system to control traffic such way?

    Sorry about that. I thought I added it. We use 2930m switches. They have been in place for a couple of years with vlans, etc.. Connections between the vlans work. I'm just looking to start segmenting things. 

    Thank you,
