an entry for the VLAN for each controller. Dell PowerConnect W recommends using the same VRRP IP used by the AP. The mobility domain named "default" is the default active domain for all controllers. If you need only one mobility domain, you can use this default domain. However, you also have the flexibility to create one or more user-defined domains to meet the unique needs of your network topology. Once you assign a controller to a userdefined domain, it automatically leaves the "default" mobility domain. If you want a controller to belong to both the "default" and a user-defined mobility domain at the same time, you must explicitly configure the "default" domain as an active domain for the controller. Navigate to Advanced Services > IP Mobility > Mobility Domain from the Dell PowerConnect W Configuration navigation pane. This page displays all currently configured IP Mobility domains. Select Add to create a new IP Mobility Domain, or click the pencil icon next to an existing profile to modify an existing domain. The Advanced Services > IP Mobility > Add/Edit IP Mobility Domain page contains the following fields, as described in Table 76: Table 76 Advanced Services > IP Mobility > Add/Edit IP Mobility Domain Field Descriptions Field Default Description General Settings Folder Top Name Other Settings Blank Set the folder with which the domain is associated. The drop-down menu displays all folders available for association with the domain. Enter the name of the domain. Active No Description Mobile IP Home Agents Define whether the IP Mobility Domain is active or inactive. Add a description for the domain (requires AOS 6.0.0.0 or later) Add Use this button to create new home agents. Once you click Add, the following additional fields appear in the Mobile IP Home Agent section. Complete these settings.  Subnet-Define the subnet mask for the IP Mobility Domain.  Netmask-Define the net mas for the IP Mobility Domain.  VLAN ID (1-4094)-Set the VLAN to be supported on the IP Mobility Domain.  Home Agent-Set the home agent for the IP Mobility Domain. When you enable IP mobility in a mobility domain, the proxy mobile IP module determines the home agent for a roaming client. Select Add to create the home agent. Select Add to create the new IP Mobility Domain, or click Save to save changes to a recon figured IP Mobility Domain. The domain is now available for use in IP Mobility profiles. Advanced Services > VPN Services For wireless networks, virtual private network (VPN) connections can be used to further secure the wireless data from attackers. The Dell PowerConnect W controller can be used as a VPN concentrator that terminates all VPN connections from both wired and wireless clients. You can configure the controller for the following types of VPNs:  Remote access VPNs allow hosts, such as telecommuters or traveling employees, to connect to private networks such as a corporate network over the Internet. Each host must run VPN client software that encapsulates and encrypts traffic and sends it to a VPN gateway at the destination network. The controller supports the following remote access VPN protocols:  Layer-2 Tunneling Protocol over IPSec (L2TP/IPSec) Dell PowerConnect W AirWave 7.2 | Configuration Guide Dell PowerConnect W Configuration Reference | 151
