Routed External Captive Portal
Gateway Gateway — Type the SCALANCE IWLAN Controller's own IP
address in that VNS. This IP address is the default gateway for the
VNS. The SCALANCE IWLAN Controller advertises this address
to the wireless devices when they sign on. For routed VNSs, it
corresponds to the IP address that is communicated to mobile
users (in the VNS) as the default gateway for the VNS subnet.
(Mobile users target the SCALANCE IWLAN Controller's interface
in their effort to route packets to an external host).
Mask Type the appropriate subnet mask for this IP address to separate
the network portion from the host portion of the address (typically
255.255.255.0).
HWC Connection Click the SCALANCE IWLAN Controller IP address. Also type the
port of the SCALANCE IWLAN Controller in the accompanying
box.
If there is an authentication server configured for this VNS, the
external Captive Portal page on the external authentication server
will send the re0quest back to the SCALANCE IWLAN Controller
to allow the SCALANCE IWLAN Controller to continue with the
RADIUS authentication and filtering.
Redirection URL Type the URL to which the wireless device user will be directed to
after authentication.
Shared Secret Type the password that is common to both the SCALANCE
IWLAN Controller and the external Web server if you want to
encrypt the information passed between the SCALANCE IWLAN
Controller and the external Web server.
Enable Authentication By default, this option is selected if the VNS Type is External
Captive Portal, which enables authentication for the new Captive
Portal VNS.

Captive Portal, which enables DHCP services for the new
Captive Portal VNS.
HWC External Captive Portal VNS
Interface Click the physical interface that provides the access to the VLAN.
Interface IP address Type the IP address of the SCALANCE IWLAN Controller’s
interface on the VLAN.
Mask Type the appropriate subnet mask for this IP address to separate
the network portion from the host portion of the address (typically
255.255.255.0).
