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.
