PwnSTAR running on Kali

[Sergey12]

Hi, i have some problem with ettercap. Now my kali machine conntected to wifi network with have def gateway 192.168.0.1, my airm is to get router password. Router i suppose uses just simple http auth, i enterd :
echo "1" > proc ....
iptables -t nat - A PREroutnig..... --to-port 8080
sslstrip -l 8080 -w test3
And in another window
ettercap -T -q -M ARP /192.168.1/ // output

But i see only such things in ettercap :

DHCP : [192.168.0.1] ASK :192.168.0.43 255.255.255.0 GW 192.168.0.1 DNS 192.168.0.1

ANy ideas? Thx( also i am sure that router admin goes on router... so i should see his creds ;( )
