3.4.1 WLAN security
In this part of the configuration, you can place limitations on the communica-
tions available to the users in the wireless network. This is done by limiting
the data transfer between user groups according to individual stations or the
protocol being used. Further, the key for the WLAN encryption is set here.
U General settings
Communications between the WLAN clients
Depending on the application, it may be required that the WLAN clients con-
nected to an access point can—or expressly cannot—communicate with oth-
er clients. You can centrally define the permissible communication for all
physical and logical networks, and consider the three following cases in do-
ing so:
D Allow data traffic: This setting allows all WLAN clients to communicate
with other stations in their own and in other available wireless networks.
D Do not allow data traffic between stations that are logged on to this access
point: In this case, WLAN clients can only communicate with mobile sta-
tions located in other available wireless networks, but not with the stations
in their own WLAN.
D Do not allow data traffic: This last variant prevents all communications be-
tween the WLAN clients.
Roaming
In addition to controlling the communication between the clients, you can de-
fine whether the mobile stations in the wireless network can change to a
neighboring access point (roaming).
Monitor stations
In particular for public WLAN access points (public spots), the charging of us-
age fees requires the recognition of stations that are no longer active. Moni-
toring involves the access point regularly sending packets to logged-in
stations. If the stations do not answer these packets, then the charging sys-
tems recognizes the station as no longer active.
Configuration with LANconfig
For configuration with LANconfig you will find the general WLAN access set-
tings under the configuration area 'WLAN Security' on the 'General' tab.
