When should Inter AP blocking be used? 
The clients connected to an access point can normally communicate with all SCALANCE 
W700 devices of the layer 2 network. 
With inter AP blocking, the communication of the clients connected to the access point can 
be restricted. Only the SCALANCE W700 devices whose IP addresses are configured in 
"Allowed Addresses" on the access point are accessible to the clients. Communication with 
other nodes in the network is therefore prevented.
