In the following link you can see the WireShark analysis at the time i try to access to some web page in this case www.infobae.com.ar from
the victim computer.
My ip_forward it s equal to 1,the arp table from the victim shows the backtrack VirtualMachine as gateway,so everything looks perfect.
But after access a web page,internet dies for all computers,and when i do the arpspoof i just point to 1 computer:
arpspoof -i eth1 -T GatewayIp Victim
arpspoof -i eth1 -T Victim GatewayIp
So maybe some one taking a look at that link can see something strange.
I really really appreciate some help.
