Wireless LAN – WLAN
11.4.5 Additional WLAN functions
Apart from the different encryption methods 802.11i/AES, WPA/TKIP or WEP
and the closed network, a variety of other functions exist for securing the
operation of a wireless network. The Redirect function provides the
convenient control over the connection of WLAN clients in changing
environments. As this function has significance to other modules of the
LANCOM LCOS, the configuration parameters are to be found outside of the
WLAN settings.
Redirect function
Clients within wireless networks often have one main aspect in common: a
high degree of mobility. The clients are thus not always connected to the same
access point, but frequently change between access points and the related
LANs.
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
client'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
automatically be redirected to the target server in the LAN. The returning data
packets are sent to the senders' addresses and ports according to the entries
in the connection statistics, which ensures the trouble-free operation in both
directions.
