Hi everybody,
 
can someone recommend me how to solve quite simple problem.
 
Assume simple setup: 
single wireless interface (wlan0), hostap in master mode,
AP adress is 192.168.1.1, 
stations use 192.168.1.2, 192.168.1.3, 192.168.1.4, 192.168.1.5
 
I want to by default deny traffic between all stations, i.e:
iw_priv wlan0 ap_bridge_packets 0
 
however, I need to allow several stations to communicate together
(i.e. 192.168.1.3 should be able to talk with 192.168.1.5).
 
Any solutions?
 
BTW: 
 
I've tried to:
1) iw_priv wlan0 ap_bridge_packets 1
2) iptables -A FORWARD -s 192.168.1.2/32 -d 192.168.1.3 -j DROP
 
to stop the traffic between station 2 and 3 but it did nothing
