If I understand correctly, you want:


o vlan 6 users to be able to access vlan 1 and vlan 2 users


o but vlan 1 and vlan 2 users can not access vlan 6 users


If the above is correct, you're not going to be able to achieve this with access lists. Think about the traffic path. It's a two-way street. For vlan 6 users to access vlan 1 and 2 users that implies that return traffic from vlan 1 and 2 users must be allowed to vlan 6.


Please let me know if I misunderstood your request!


Thanks, Robin.

Correct me if I'm wrong, but couldn't you control this with a reflexive list from VLAN 6 to VLAN 1 & 2? Something like, slap all traffic from VLAN 6 incoming into a list, then evaluate the reflexive list outgoing, deny everything else?


I have this setup for my 871 at home, works just fine to block traffic.
