Virtual Access Points
The IP60 appliance enables you to partition the primary WLAN into virtual access points (VAPs). A VAP
is a logical wireless network behind the IP60 appliance and is a type of VLAN (see
Configuring VLANs on
page 126). Like other types of VLANs, VAPs are isolated from each other and can have separate security
policies, IP network segments, and Traffic Shaper settings. This enables you to configure separate policies
for different groups of wireless users.
For example, you could assign different permissions to employees and guests using your company's
wireless network, by defining two VAPs called ―Guest‖ and ―Employee‖. The Guest VAP would use
simple WPA-Personal encryption, and the security policy would mandate that stations connected to this
network can access the Internet, but not sensitive company resources. You could configure Traffic Shaper
bandwidth management to give stations in the Guest network a low priority, and by enabling Secure
HotSpot on this network, you could define terms of use that the guest users must accept before accessing
the Internet. In contrast, the Employee VAP would use the more secure WPA2-Enterprise (802.11i)
encryption standard and allow employees to access company resources such as the intranet.
You can configure up to three VAPs, in addition to the primary WLAN. For information on configuring
VAPs, see
Configuring VAPs on page 209.
Wireless Distribution System Links
The IP60 appliance enables you to extend the primary WLAN's coverage area, by creating a Wireless
Distribution System (WDS). A WDS is a system of access points that communicate with each other
wirelessly via WDS links, without any need for a wired backbone. For example, if your business has
expanded across two buildings, and a single access point no longer provides sufficient coverage, you can
add another access point that acts as a repeater. If it is impractical or costly to run wires between the access
points, you can connect them by configuring a WDS that includes both access points.
WDS is usually used together with bridge mode to connect the networks behind the access points. For
example, if you have two network segments, each of which is served by a different access point, you can
bridge the two network segments over WDS links. The network segments will communicate with each
other wirelessly via their access points and act as a single network. For information on bridge mode, see
Using Bridges on page 157.
WDS links are considered a type of VLAN (see Configuring VLANs on page 126). Therefore, they can
have separate security policies, IP network segments, and Traffic Shaper settings.
