Enabling portal authentication

	CAUTION: Do not enable portal authentication on both an interface and a service template.

You must first enable portal authentication on an access interface or service template before it can perform portal authentication for connected clients.

With portal authentication enabled, the device searches for a portal authentication server for a received portal packet according to the source IP address and VPN information of the packet.

• If the packet matches a locally configured portal authentication server, the device regards the packet valid and sends an authentication response packet to the portal authentication server. After a user logs in to the device, the user interacts with the portal authentication server as needed.

• If the packet does not match a portal authentication server, the device drops the packet.
