Okay, now I've following situation:
Notebook:
Wlan0: 192.168.1.155 gw: 192.168.1.1
Eth0: 172.16.42.42 gw: 172.16.42.1
Pineapple:
Eth0: 172.16.42.1
I can ping the ip 192.168.1.155 from the pineapple (putty/ssh), but I get no response when I ping the ip 192.168.1.1!
Ip4 forwarding is 1
Iptables are configured
I've no idea what to do!
