sickduck Posted August 27, 2012 Share Posted August 27, 2012 Does anyone know how to mirror the LAN port from the WAN port? What I am trying to do is to monitor all wireless traffic in realtime from Wireshark. (I want this in realtime so I can't use tcpdump.) The pineapple gets internet from the WAN port. I used network manager to set up the internet sharing to br-lan. I would like the LAN port to be a monitor/mirror port to see the wireless traffic. I did some googling and came up with the following iptables commands but it doesn't seem to be working. Any ideas, please? iptables -A PREROUTING -t mangle -j ROUTE --gw 172.16.42.42 --tee iptables -A POSTROUTING -t mangle -j ROUTE --gw 172.16.42.42 --tee Quote Link to comment Share on other sites More sharing options...
Infiltrator Posted August 28, 2012 Share Posted August 28, 2012 Yes, you need a layer 3 switch or a network switch that has port mirroring capabilities. Usually a smart or managed switch will have this feature. Quote Link to comment Share on other sites More sharing options...

Usually a smart or managed switch will have this feature. If I understand the OP correctly, that is wrong. If you take a look at Digininja's Interceptor, you will not find the exact solution but a similar one. I am currently working on a pineapple version for just this though.
