Currently we have a network that is not physically seperated but seperated using VLANS. Servers and workstations are in a VLAN, IP Phones are in a VLAN. We host a web application for our customers and we would like to seperate the servers that host the web app from the rest of the devices physically. We were thinking about putting a router in between the customer facing servers and the rest of the backoffice enviroment. Is there a better way of doing this? Thanks in advance.
