anyone here tried to use burp suite proxy lately in bt5r2/r3??because it's not working for me.

i have a win7 connected to fake Ap with dnsspoof running,
it's send http(s) request in port 80/443
,packets are shown in wireshark dest port 80, but in burp there no intercept going on,port 80/443 are added in options et support invisible proxing for unaware-proxy client...

but when i use it in my browser with proxy setting localhost:8080
its work(fake certificat show up)

i tried to redirect packets to port 8080

iptables -A PREROUTING -t nat -i mitm -p tcp --dport 80 -j REDIRECT --to-port 8080

but connexion in victim's pc stop working

is there any way in wireshark to make sure dnsspoof is working?
