Hello community,

I am new to this board and first I will say hello. I am not a English native speaker but I hope you can understand me.

Since a couple of days I spend time to understand MITM attacks. I tested it with Backtrack 5R3 on one of my computers (arpspoof and sslstrip) and it works.
Now I have the situation that one of my victim machines goes over a proxy-server into the internet. With this environment the MITM attack doesn't work. What can I do to sniff the traffic when the victim use a proxy-server?

Thanks in advance,
