OK so a physical subnetted network is 'safer'/'more secure' than a VLAN network. I'm still not getting the difference between a virtual and a physical LAN. Can anyone give me an example of say a company with two branches in different locations with each branch have its own sales and accounts department. I would subnet my IP such: Office A 192.168.0.x Office B 192.168.1.x The departments of each office would have IP's from their respective subnet. Sales A 192.168.0.1 Sales B 192.168.1.1 Accounts A 192.168.0.2 Accounts B 192.168.1.2 Make sense? tnx for the help
Different locations? Then you want two physical LANs, each with their own address block, and you might use a third (tiny) block to manage the WAN link between locations. Where you would use VLANs is to separate different departments (or organizational units or security contexts) *in the same physical vicinity*. Instead of mounting two adjacent devices (physical), you install a single device and ("logically") partition it (virtual).
