[Guest kaede]

hi, i trying to test out arpspoof at my company network (gonna permission for that)

previous when i run no a LAN the thing run fine

The problem come as we change to WLAN, in my linux server, i try running this command: arpspoof -i eth1 -t 192.168.0.3 192.168.0.1

(eth0: my LAN network card, eth1: wireless network card)

Anyone encounter this problem, need some solution over here, thankz
