Hello People,
I have a little question:
I have two laptops that have 802.11 wireless cards. I am developing some application that essentially perform sniffing functions using wireless cards in promiscuous mode. To test my code, I need those two laptops not to "see" each other (--> I do not want the wireless card of laptop A, which is operating in promiscuous mode to process packets coming from laptop B) and I tought to do it using iptables. so on laptop A i added the following rule:
iptables -A INPUT -mac --mac-source MAC_ADDRESS_LAPTOP_B -j DROP
and on laptop B I added the rule:
iptables -A INPUT -mac --mac-source MAC_ADDRESS_LAPTOP_A -j DROP
I just executed my first tests and the feeling I got is that, for example, the wlan card of laptop B still passes through the packet coming from laptop A.
Can anyone confirm this analysis? If I am right, can anyone give me a hint to possibly workaround this?
Thank you very much
Claudio
