8. Click Next. The Filtering screen is displayed.

9. On the Filtering screen, do the following:

– In the Filter ID drop-down list, click one of the following:

- Default — Controls access if there is no matching filter ID for a user.

- Exception — Protects access to the SCALANCE IWLAN Controller’s own interfaces,

including the VNSs own interface. VNS exception filters are applied to user traffic

intended for the SCALANCE IWLAN Controller's own interface point on the VNS.

These filters are applied after the user's specific VNS state assigned filters.

10. In the Filter table, select the Allow or Deny option buttons for each filter if applicable, and

then select the Enable checkbox accordingly.

Field/Button Description

DHCP Option In the DHCP Option drop-down list, click one of the following:

Use DHCP Relay — Using DHCP relay forces the SCALANCE

IWLAN Controller to forward DHCP requests to an external DHCP

server on the enterprise network. DHCP relay bypasses the local

DHCP server for the SCALANCE IWLAN Controller and allows the

enterprise to manage IP address allocation to a VNS from its

existing infrastructure.

DHCP Servers — If Use DHCP Relay was selected, type the IP

address of the DHCP server to which DHCP discover and request

messages will be forwarded for clients on this VNS. The

SCALANCE IWLAN Controller does not handle DHCP requests

from users, but instead forwards the requests to the indicated

DHCP server.

The DHCP server must be configured to match the VNS settings.

In particular for a Routed VNS, the DHCP server must identify the

SCALANCE IWLAN Controller's interface IP as the default

Gateway (router) for the subnet. (Users intending to reach devices

outside of the subnet will forward the packets to the default

gateway (controller) for delivery upstream.)

Local DHCP Server — If applicable, edit the local DHCP server

settings.

DNS Server Type the IP Address of the Domain Name Servers to be used.

WINS Type the IP address if the DHCP server uses Windows Internet

Naming Service (WINS).
