Answer : VLAN vs VPN

A VLAN is a virtual way to create and maintain LAN networks on a switch or router.  You can have for instance one switch with 24 ports, in which you define the first 12 to be one LAN VLAN, and the other a DMZ VLAN.  The programming in the switch will make sure that, while you are using just one hardware switch, the switch acts like two independent switch connected to other networks.  A router/switch can "fake" routing and 2 or more separate switches in just one hardware box.

A VPN is a way to connect two networks in a secure way to each other, over an insecure network such as the internet.  On both sides, you set up tunnel "entrances" and data entering the VPN tunnel through one side will be encrypted and encapsulated and sent to the tunnel 'exit' on the other end.
