The redirect function assist the applications being used by the WLAN clients
to find the correct target computer in the LAN automatically. If a WLAN cli-
ent's HTTP request from a certain logical wireless network should always be
directed to a certain server in the LAN, then a filter setting for the appropriate
protocol with the action "redirect" will be set up for the desired logical WLAN
interface.
All requests with this protocol from this logical wireless network will automat-
ically be redirected to the target server in the LAN. The returning data pack-
ets are sent to the senders' addresses and ports according to the entries in
the connection statistics, which ensures the trouble-free operation in both di-
rections. Further information to the configuration of the protocol filter can be
found ’Protocol filter’ → page 55
U IEEE 802.1x/EAP
The international industry standard IEEE 802.1x and the Extensible
Authentication Protocol (EAP) enable access points to carry out reliable and
secure access checks. The access data can be managed centrally on a RA-
DIUS server and can be called up by the access point on demand.
This technology also enables the secure transmission and the regular auto-
matic changing of WEP keys. In this way, IEEE 802.1x improves the security
of WEP.
The IEEE-802.1x technology is already fully integrated in Windows XP. Cli-
ent software exists for other operating systems.
