Is it at all possible, with the ER7212PC v.1, to setup three VLANs, each on its own physical port, while keeping them from accessing each other (ie. Ping), without using an additional switch? I was able to do this with the ER605 v1, but can't figure it out with the ER7212PC v1. Ports have been assigned to the correct PVID respectively and Bidirectional Deny ACLs have been created as Switch ACLs, but Pings keep going back and forth.
