I attempted to do this but couldn't get traffic to flow between the two vlans. I may have to revisit - but setting them all to the same security and applying the same-security traffic - allows the conversation and then I added access-lists denying traffic seems to be one solution - although attempting to keep the config as simple as possible is the goal. Yep - layer 3 would be optimal. Unfortunately that's not in the cards currently. I'll test this again with the higher security level to see if I can get this to work. thx!

We have a 5512x that we've setup with an Ether-channel and multiple subinterfaces (vlans). Our goal is to be able to allow one vlan to communicate to all other vlan's through the 5512 but block the inter-vlan communication for the the other vlans. We have been attempting to accomplish this by having all vlan's on the same security level - while utilizing access-lists and tcpbypass. So far this isn't working and I'm not sure what the issue(s) could be (perhaps numerous). We do not have a layer 3 switch. Please advise.
