  • ACL’s can accomplish it if that’s your only goal, but there are other benefits of vlans for security and privacy. For example an ACL works at layer 3, so it won’t block other nosy devices on your network from seeing everything else via layer 2 and then reporting back what it finds. VLANs also make it easy to use different security policies for each network if you do any sort of IDS/IPS as I do.
