Before You Begin
Before you configure your portal, you may need to configure VLANs, SSIDs, and
users. Read the following information to determine what steps may be needed to
achieve your goals.

VLAN Setup

No special VLAN configuration is required for a Captive Portal, but you may want
to consider the points below before proceeding. To configure VLANs, use the
Networking > VLAN page..
• Each SSID is associated with a VLAN. You can use the pre-configured
VLANs (DEFAULT, GUEST, and VOICE) or add a custom VLAN.
• You may want to associate a VLAN, such as the GUEST VLAN, with a
security zone so that you can configure appropriate security policies. For
example, you can apply URL filtering policies to the zone to prevent access
to certa in types of websites.
• A Captive Portal must be associated either with a single SSID or with a
VLAN. If you want to enable a portal for users of multiple SSIDs, you will
need to assign them all to the same VLAN. You can use a pre-configured
VLAN or can create a VLAN for this purpose.
