Hey i created that tutorial. with that setup you can run SSLstrip. I am using backtrack pre-final. I first updated backtracks dhcp3.

The way i have my fon setup is:

I statically assigned the webif interface to so it would not interfere with dhcp3 running as the gateway and dhcp server. Depending on what range you want this it could be anything

to check you logs:

cat /var/log/syslog

that is show any errors with DHCPD3
