I have a difficulty with Ettercap and Sslstrip. If I uncomment iptables on etter.conf, ettercap take over ssl, and the browser gives certificate errors. If I keep ignoring the errors, I ultimately get signed in. If I keep the iptables commented on etter.conf, sslstrip seem to get hold of over ssl connections and catches the login information. Nonetheless, the browser gets redirect back to sing up page. Basically, I can't log in. Seeing at the log, the whole thing is forwarded and spoofed appropriately. How can I overcome this problem?
