Configuring a VLAN
Use the Networking > WAN > VLAN page to configure a Virtual LAN (VLAN).
VLANs allow you to segregate and isolate traffic. A PC on one VLAN cannot
access the network resources on other VLANs.
The security appliance predefines three VLANs:
• A native VLAN (DEFAULT) , with VLAN ID 1 and IP address 192.168.75.1. By
default, this VLAN is in the LAN zone.
• A guest VLAN (GUEST), with VLAN ID 2 and IP address 192.168.25.1. By
default, this VLAN is in the GUEST zone.
• A voice VLAN (VOICE) with VLAN ID 100 and IP address 10.1.1.2. By default,
this VLAN is in the VOICE zone.
You can change the settings for predefined VLANs or add new VLANs to meet
your business needs.
NOTE Up to 16 VLANs can be configured on the security appliance.
