There have been several posts in this discussion that mention reflexive access lists. And this relates to a fundamental problem with what you want to achieve. As an example you want a device in vlan 1 (perhaps it is 192.168.1.11) to communicate with a device in vlan 3 (perhaps it is 192.168.3.33). Assuming that you will use an access list inbound on interface vlan 3 to filter the traffic it will receive an IP packet whose source address is 192.168.3.33 and destination is 192.168.1.11 - should the access list permit or deny this packet? The answer is deny if the packet is from 192.168.3.33 initiating some to vlan 1. But the answer is permit if this is 192.168.3.33 responding to something initiated from vlan 1. How does the access list determine whether this is a response or not?
To really achieve your requirements requires doing stateful inspection in which we would know who initiated the traffic. I dont believe that your switch supports doing stateful inspection.
