VLAN Configuration The security appliance supports Virtual LANs (VLANs), which allow you to segregate the network into LANs that are isolated from one another. The default configuration provides for a data VLAN and a voice VLAN, which can be treated like two separate networks. You can change the settings for the default VLANs, and you can add new VLANs, for up to a total of 16 VLANs. For example, if you need a guest network for visitors to your site, you can create new VLAN. Any PC that is connected to the specified LAN port is on a separate VLAN and cannot access other VLANs, unless you enable inter VLAN routing.
