External Captive Portal Basic Settings Page - Fields and Buttons

Field/Button	Description
Enabled	By default, the Enabled checkbox for the new VNS is enabled. A VNS must be enabled for it to be able to provide service for mobile user traffic.
Synchronize	Synchronize — Enable automatic synchronization with its availability peer. Refer to Using the Sync Summary for information about viewing synchronization status. If this VNS is part of an availability pair, Extreme Networks recommends that you enable this feature.
Name	Identifies the name of the VNS.
Category	Identifies the VNS category.
SSID	Identifies the SSID assigned to the VNS.
Authentication Mode	Click External Captive Portal
Mode	Click the VNS Mode you want to assign: Routed is a VNS type where user traffic is tunneled to the controller. Bridge Traffic Locally at EWC is a VNS type where user traffic is tunneled to the controller and is directly bridged at the controller to a specific VLAN. With this VNS type, mobile users become a natural extension of a VLAN subnet. For each Bridge Traffic Locally at EWC VNS that is created, a VLAN needs to be specified. In addition, the network port on which the VLAN is assigned must be configured on the switch, and the corresponding controller interface must match the correct VLAN.
Routed External Captive Portal
Gateway	Gateway — Type the controller's own IP address in that VNS. This IP address is the default gateway for the VNS. The 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 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).
EWC Connection	Click the controller IP address. Also type the port of the 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 controller to allow the 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 controller and the external Web server if you want to encrypt the information passed between the 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.
Enable DHCP	By default, this option is selected if the VNS Type is External Captive Portal, which enables DHCP (Dynamic Host Configuration Protocol) services for the new Captive Portal VNS.
EWC 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 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).
VLAN ID	Type the VLAN tag to which the controller will be bridged for the VNS.
EWC Connection	Click the controller IP address. Also type the port of the 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 request back to the controller to allow the 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 controller and the external Web server if you want to encrypt the information passed between the 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.
Enable DHCP	If applicable, select this checkbox to enable DHCP authentication for the new Captive Portal VNS.
